Lesson: ATP Check Using the Example of Sales and Distribution

Lesson: ATP Check Using the Example of Sales and Distribution Lesson Overview In this lesson, you will learn about the ATP check together with the sales order and outbound delivery in more detail. It discusses the concept of the ATP check along with how to interpret the results and configure the Customizing settings.

Lesson Objectives After completing this lesson, you will be able to: • • • • • •

Business Example When you create a sales order, you can confirm delivery of the goods on the requested delivery date only if they are available for all processing activities before the delivery is issued. So that you can reliably confirm a delivery, availability has to be checked on the basis of the ATP quantity as part of order processing and generating the outbound delivery.

Concept of the ATP Check

Figure 1: Concept of the ATP Check

The ATP availability check is a function that can be executed for: sales documents, outbound deliveries, planned orders, production orders, service orders, stock transport requisitions, stock transport orders, stock transport scheduling agreements, subcontracting items for purchase orders, reservations, and stock postings. The ATP check informs the user whether all required materials are available for sales or shipping, production, and goods movements. At the same time, it prevents the required material from being displayed as available for other requirements. The aim is to provide reliable delivery confirmations, in other words, to confirm materials, quantities, and dates for the customer (both internal and external customers). The basic concept of the check based on the ATP quantity is summarized as follows: Incoming requirements (for example, customer requirements or component requirements in manufacturing) are checked against the “cumulated ATP quantity” for the requirement date. If the cumulated ATP quantity for the requirement date is sufficient, the requirement can be confirmed. At the same time, the requirement reduces the cumulated ATP quantity. The quantity is therefore “reserved” for the requirement and is not available for other requirements. You can use the Customizing settings to specify the stocks and stock changes that are taken into account when the ATP quantity is calculated and availability checked.

Interpreting the Results of the ATP Check

Figure 2: Availability Check

If the availability check for the order is successful, the system confirms the required material and quantity for the required date. In this case, the user does not notice the availability check. The result is a confirmed schedule line in the sales order. If the availability check is unsuccessful, the system response is dependent on the Customizing settings. The system can branch to the Availability Control screen or automatically select the delivery proposal specified in the Customizing settings for Availability Check Default Values. On the Availability Control screen, the system informs the user of the quantities that can be confirmed as required and those that cannot be confirmed as required, and if possible, proposes an alternative delivery. Note: Fix Quantity/Date: If the customer or order processor accepts the delivery date and quantity proposed and confirmed by the system, this quantity and date can be fixed. The system then transfers the requirement to materials planning so that the confirmed date and quantity can be met. The date and quantity originally required are not forwarded to materials planning. If you do not select the Fix Qty/Date field, the delivery date and confirmed quantity are not fixed. If materials can be either produced or procured more quickly, you may be able to deliver the materials closer to the required delivery date, that is, earlier than the date confirmed by the system. However, the delivery quantity and date may also be negatively affected.

2009

SCM671

Figure 3: Default Values in Customizing

In the Avail. Check Rule field, you can activate or deactivate the Availability Control screen for sales document processing. If the screen is deactivated, the end user cannot manually select a delivery proposal if the availability check is insufficient. Therefore, Customizing settings must be configured to specify how the system is to respond. Is the system to select one-time delivery, complete delivery, or delivery proposal automatically in the background? If the Availability Control screen is active, you still have to define how the system responds if the availability check is insufficient for functions that run in the background and that check availability (for example, rescheduling). You can also control whether the Fix Qty/Date parameter on the Availability Control screen is selected by default.

SCM671


Figure 4: Order Schedule Lines

The result of the availability check is documented in the order schedule lines. In the sales documents, the required material, quantity, and date are entered at item level. For each item, there is at least one schedule line that the system generates automatically. If the required quantity and date can be confirmed on the basis of the availability check and shipping and transportation scheduling, this is documented in the system by a confirmed schedule line for the order item. If the required quantity and date cannot be confirmed, and the availability check does not return a delivery proposal, an unconfirmed schedule line may exist in extreme cases. Unconfirmed schedule lines cannot be delivered. This kind of situation therefore requires immediate backorder processing. In situations in which the required quantity cannot be confirmed for the required date, the system usually generates delivery proposals based on the forecasted ATP quantities, and these proposals are then documented as additional schedule lines for the order item.

SCM671

You can set the complete delivery indicator in the sold-to party master record, and this is then transferred to the document header of the sales document. It specifies that a document and all of its items must be delivered in full. The partial delivery indicator for the document items can be proposed from the sold-to party master record or the customer material info record. 1. The information in the customer material info record takes precedence. It refers to the full or split delivery of several schedule lines for an item. The following partial delivery agreements are possible at item level: •

_ Partial delivery allowed

•

A Create a delivery with qty greater than zero

•

B Create only one delivery (also with quantity = 0)

•

C Only complete delivery allowed

•

D No limit to subsequent deliveries

The complete delivery at header level and partial delivery at item level indicators can be changed manually when you process sales documents.

Declarations about the availability situation can be made only on the basis of the ATP quantity. Transaction CO09 “Availability Overview” can be used for this. The stock/requirements list (transaction MD04) and the stock overview (transaction MMBE) cannot be used for declarations about availability. If they are used, the availability situation is often misinterpreted.

Figure 7: Digression: Material View and Enhanced Material Search

In Customizing, you can activate the material view or the material view and enhanced material search for the sales order application. Using the material view function, you can display detailed material data without having to access the material master directly. In the material view for material of one or more sales document items, you can display the ATP quantity based on the current date across several plants. You access the material view screen by selecting one or more sales order items and choosing the icon with the quick info Display Material View. You can specify the plants to be evaluated (the “associated plants”) for the plant of the order item. The possible selection of plants ranges from the selection of only the delivery plant of the order item to all plants that are assigned to the sales organization of the order or all plants that are assigned to the company code of the operation. You can also analyze all plants in a region or “all” plants for which the material is maintained. Using the transaction WSD_CBP “Display Close-By Plant Assignments,” you can also freely specify the plants that are to be analyzed in the material view in conjunction with the availability check. The concept of the extended material search is to enable you to find materials quickly and efficiently. The extended material search can therefore be used as an alternative to the F4 material search in the sales documents. Along with other search criteria, you can perform a “free-text search” and a material search with

2009

SCM671

key words. In the search result of the extended material search, the ATP quantity can be displayed across plants for each material. To select plants to be analyzed, the same options as for the material view are available. A traffic light immediately informs you whether the material has been created in the respective plant and whether it is available in that plant. In the result of the extended material search, you can enter the required order quantity for a valid combination of material and plant (material is maintained in the plant), and the required materials can then be transferred to the order as order items.

Using the ATP Check in Sales and Distribution

Figure 8: Using the ATP Check in the Sales Process

In the sales process within the SAP system, the availability check can be used in all sales documents that have the “schedule line” level. It can also be used in outbound deliveries. Once availability has been checked in the initial sales document, a new check may be useful at the time the delivery is created since the ATP situation may have changed in the meantime.

Figure 9: Activating the Availability Check

So that the availability check is carried out as part of document processing for sales and outbound deliveries, this function must be “activated.” If necessary, the availability check can be activated only for specific materials or material groups, or for selected operations. Whether the material or operation is relevant for the check depends on the various Customizing objects and parameters, as well as the corresponding fields in the material master record. The following objects may be relevant: requirement class, schedule line category, delivery item category, checking group, strategy, requirement type, MRP group, strategy group, and MRP type.

2009

SCM671

Figure 10: Deciding on the Check Method

Once you have decided whether availability has to be checked, you also have to decide which check method to use.

Figure 11: Activating and Selecting the Check Method

If an ATP check is expressly intended, it is essential that the availability check is activated in the method at the level of the requirement class. For sales documents, the availability check must also be active in the relevant schedule line categories; for outbound delivery documents, it must be active in the relevant delivery item categories. If an availability check is not intended at the level of the requirement

12


2009

SCM671


class, it cannot be activated at schedule line or item level. However: If the availability check is active at the level of requirement classes, it can still be deactivated at schedule line or delivery item level. In addition, the ATP check can be activated and deactivated using the checking group. The checking group is defined in the material master and groups materials in terms of the requirements transfer and the ATP check. Consequently, there is an additional option of activating and deactivating the ATP check in relation to the material.

Figure 12: Determining the Requirement Class in Relation to the Material

Whether an availability check is carried out may be dependent on the material or operation. You can define this using the requirement class. Determining the requirement class using the material: •

• •

First, an attempt is made to determine a strategy using the strategy group from the material master. If the strategy group is not maintained, the MRP group is used to determine it. If the MRP group is not defined, the system uses the material type instead of the MRP group to determine the strategy group (the material type has to be maintained as the MRP group). A requirement type for customer requirements is determined using the strategy. The requirement class is determined using the requirement type for the customer requirement.

The availability check for the requirement class is then activated in the required method.

2009


13


SCM671

Figure 13: Determining the Requirement Class in Relation to the Operation

Determining the requirement class using the operation: •

•

If a requirement class cannot be determined using the material, the system attempts to determine a requirement type or class using the item category (document) and the MRP type (material master). If this is not possible, the system attempts to determine a requirement type or class using only the item category.

If all of the attempts to determine a requirement class fail or if the availability check is deactivated for the requirement class determined, the operation is not relevant for the availability check. Note: The Source field can be used to choose an alternative search strategy. You also have the option to prioritize the determination of the requirement type/class using transactions.

Figure 14: Automatically Determining the Schedule Line Category

If an ATP check is to be carried out in the sales document, it must be active in the relevant schedule line categories. The system uses two steps to automatically determine the schedule line category to control the order schedule lines: First, it tries to determine the schedule line category using the key combination of item category and MRP type. If a schedule line category is not found, the system then finds the schedule line category using only the item category. In each case, automatically determining the schedule line category is therefore based on the order item category that was previously determined. This is determined on the basis of the following criteria: • • • •

2009

1. Order type of the document 2. Item category group from the material master record 3. Use of the item that is implemented within the program for specific business transactions and functions 4. Item category of a higher-level item (in the case of a subitem)


15


SCM671

Figure 15: Determining the Delivery Item Category

In Customizing for the delivery item category, you can deactivate the availability check for delivery items. The item category of a delivery item is determined as follows: When you copy an order item to a delivery, the system copies the key of the order item category to the delivery item. The system cannot copy an (order) item category for order-independent items in the delivery (for example, packaging material in the delivery) or for a delivery without a reference to an order (for example, delivery type LO). In this case, the system determines an item category for the delivery according to the assignments specified in Customizing. Determining the item category in the delivery is very similar to determining the item category in the order. To determine the item category, the system takes into account the delivery type as well as the item category group (from the material master of the item). Additional use is set internally for some functions.

Controlling the ATP Check

Figure 16: Check Logic

The basic check logic of the ATP check is hard-coded and cannot be changed in Customizing. The ATP check is successful if a sufficient, cumulated ATP quantity is available on the material availability date. You can display the stock, receipt, and requirement information necessary to calculate the ATP quantity, as well as the relevant points in time, in a time series. Programming dictates that the system always attempts to fulfill requirements with the most recent receipt. On the basis of this logic, along with the stock, receipt, and requirements information, and your time points, the system calculates and displays the cumulated ATP quantity from today to a given point in the future. To consolidate your understanding of the ATP check, here is a summary of the most important points: • • • • • • •

2009

The ATP check is successful if a sufficient (cumulated) ATP quantity is available on the material availability date. The scope of the ATP quantity is defined individually for each company based on the operation or product (scope of check). The basic check level is at plant or storage location level. The check can be carried out regardless of whether the replenishment lead time is used. The ATP check in SAP ECC is accurate to the day. Issues always try to consume the most recent receipt first. When the check is carried out, cumulated requirements and confirmed quantities can be taken into account.


17


SCM671

Figure 17: Controlling the ATP Check

The type and scope of the ATP check is defined in Customizing for “Availability Control”. This defines the ATP quantity calculation and the level of the check, and determines whether the ATP check is carried out with or without the replenishment lead time.

Figure 18: Selecting Check Control

The “availability control”, that is, the type and scope of the ATP check, can again depend on the material, the material group, and the operation. The checking group is one feature of determining the “availability check control.” For the ATP check,

18


2009

SCM671


materials are grouped using the checking group, whereby a specific checking group is assigned to the required materials in the material master. New checking groups can be defined in Customizing if necessary. The second feature for determining the “availability check control” is the checking rule. This is used to distinguish operations in terms of the ATP check. The assignment of document type and checking rule is hard-coded in the “Sales and Distribution” application. In general, checking rule A is assigned to the sales document and checking rule B is assigned to the delivery document. However, company-specific requirements can be modeled in the “Sales and Distribution” application using the user exit RV03VFZZ.

ATP Quantity The basic concept of the check based on the ATP quantity is summarized as follows: The requirement date of incoming requirements (for example, customer requirements or component requirements in manufacturing) is checked against the cumulated ATP quantity. If the ATP quantity for the requirement date is available, the requirement can be confirmed. At the same time, a confirmed requirement reduces the cumulated ATP quantity. The quantity is therefore “reserved” for the requirement and is not available for other requirements. The stocks and stock changes that are taken into account when the ATP quantity is calculated and the availability is checked depend on the scope of the check. The document processor can display the check scope of a document when processing the document. This is defined in Customizing

Figure 19: Defining the Scope of Check

2009


19


SCM671

In the “availability check control,” you also define the scope of the check. That is, you specify which stock segments, planned requirements, and planned receipt elements are included in the ATP quantity calculation. The following elements can be included in the availability check: • •

Stocks: unrestricted-use stock, safety stock, stock in transfer, stock in quality inspection, and blocked stock. Receipts/issues: purchase orders, purchase requisitions, planned orders, production orders, reservations, dependent reservations, dependent requirements, sales requirements, and delivery requirements.

Receipts in the past: If planned receipts are included in the ATP quantity calculation, the following situations may arise. At present, there may be planned receipts that were expected in the past. These receipt elements should already have been added to stock. However, they are still planned receipts with a planned receipt date in the past. In Customizing for the “availability check control,” you can now decide whether this receipt element is to be included in the ATP quantity calculation. In either case, you can activate an additional warning message for the user. For operations that generate special stocks (such as make-to-order production, consignment processing, or returnable packaging processing), availability is checked against the special stock using the specified scope of check in conjunction with the respective special stock indicator from the requirement class. Since various, operation-based scopes of check can be defined, they must be consistent along the process chain. If, for example, the checking rules dictate that the availability check in sales documents is to include both sales and delivery requirements, but that the availability check in deliveries is to include delivery requirements only, there is a danger that quantities already “reserved” by sales documents may be displayed as available for the availability check of deliveries. As a result, there may be a backlog of sales documents in some cases. Note: In SAP SCM APO, the scope of the product availability check can be defined in much greater detail using ATP categories.

20


2009

SCM671


Check Level of the ATP Check

Figure 20: Where Is ATP Checked?

Availability for sales documents and deliveries is generally checked at plant and storage location level. If the material is handled in batches, an additional check is carried out at batch level. However, you can configure the Customizing settings to deactivate the check at storage location level. In sales documents, availability is checked in the plant of the order item. The plant is usually determined automatically (location determination) based on the master data. Any master data in which the delivery plant can be defined is accessed in the following sequence: •

1. Customer-material info record (detailed view)

•

2. Customer master record of the goods recipient (Sales Data: Shipping tab page)

•

3. Material master record (Sales: Sales Org. 1 tab page)

If you enter the delivery plant manually during order processing, your entry will overwrite the default value for location determination. Caution: Availability for a sales document item is checked in the delivery plant of the item; if a storage location is defined in the order item and the storage location check is active, the check is carried out in this storage location only. An automatic, cross-plant availability check is not

2009


21


SCM671

available in SAP ERP. However, the Other Plant option on the availability control screen of the order allows you to manually include multiple plants in the availability check, not only the delivery plant of the item. Note: Besides determining locations in the ECC system based purely on master data as described above, you can also use the SCM APO system to determine locations and check availability based on rules (for more information, see course SCM 670 Global Available-to-Promise). This allows you to check availability automatically and across plants. The storage location is not automatically determined in sales documents. The availability check of sales documents is therefore specific to a storage location only if the storage location is specified with the document item either manually or by configuring the system. Availability for deliveries is checked at the level of the delivery plant or storage location of the delivery item if the check at storage location level is active. The storage location can be and generally is determined automatically in deliveries. Depending on the attributes of the requirement (plant, plant/storage location, plant/batch, plant/storage location/batch), availability is checked at different levels. For example, if a requirement applies only to a plant, it is sufficient to restrict the stocks, receipts, and issues to plant view. However, if the issue refers to a batch or storage location, batch and storage location stocks must be included along with the plant stock. For example, if a batch is specified, the check is carried out on two levels: first against the batch and then against the plant stock. If a batch and a storage location are specified, the check is carried out on four levels: first against the batch storage location, then against the batch, then against the storage location, and finally against the plant stock. Caution: The organizational level with the lowest ATP quantity determines the result of the check. Note: If the storage location is excluded from materials planning or is planned separately, the additional check at plant level is not carried out since this storage location stock is not included in the plant stock. Sales order stocks and project stocks are managed separately in the system and are not included in the plant stock. If material is issued from sales order stock or project stock, the check is carried out for this individual stock only. A two-level check is not carried out.

22


2009

SCM671


Figure 21: Customizing the Check Level

In Customizing for the “availability check control,”, the check at storage location level can be deactivated in the “Storage Location Inspection” area. If the No Stor. Loc. Inspectn indicator is not set, availability is checked at the level of the storage location. This assumes however, that the requirement contains storage location information. If this is not the case, the check is carried out at plant level only. The requirement must always contain plant information. If the No Stor. Loc. Inspectn indicator is set, availability is checked at plant level. This is the case, even if the requirement contains storage location information. Note: If a storage location is excluded from materials planning or is planned separately, the check without storage locations cannot be activated.

Figure 22: Example: Checking at Plant Level

Once the ATP quantity has been checked, the result is as follows: Requirement 1 in the amount of 1,200 pieces can be confirmed in full. To confirm this requirement, 500 pieces are obtained from receipt 1 and the remaining 700 pieces are removed from the plant stock. The plant stock can still provide an ATP quantity of 300 pieces for future requirements.

2009


23


SCM671

Figure 23: Example: Checking at Storage Location Level

The plant stock of 1,000 pieces comprises the stock in storage location 1 in the amount of 800 pieces and the stock in storage location 2 in the amount of 200 pieces. Requirement 2 for 500 pieces is to be removed from storage location 1. At present, this storage location contains 800 pieces. Requirement 2 still cannot be confirmed in full since only 300 pieces of plant stock are available at plant level. Requirement 2 is therefore confirmed in the amount of 300 pieces. If the system confirmed the full requirement quantity of 500 pieces, the availability of confirmed issue 1 (for which the issue storage location is not specified and that removes items from the plant stock) would be compromised since it would be 200 pieces short.

Time of the ATP Check

Figure 24: For which point in time is the ATP check carried out?

24


2009

SCM671


The availability check is based on the material availability date. The availability check in the order presupposes delivery and transportation scheduling. First, the material availability date is calculated (by examining the latest point in time at which the material must be available in the warehouse so that there is sufficient time remaining for the shipping process, and so that the goods can be delivered to the customer on the required delivery date).

Figure 25: Backward Scheduling

For backwards scheduling, the customer’s requested delivery date is used to calculate the material availability date and the transportation lead time. The outbound delivery must be created at the earliest of the two dates (selection date for the outbound delivery). The material must be available on the material availability date since only then can the shipping process begin. If both dates are after the date on which the order was created and the material is available on the material availability date, the customer’s requested delivery date can be confirmed. A schedule line is created for the sales document item. The date of the schedule line displays the confirmed delivery date, which is the same as the customer’s requested delivery date. If one of the two dates is before the order date or if the material is not available on the material availability date, the requested delivery date cannot be confirmed. Therefore, the system attempts to determine the next possible delivery date (forward scheduling).

Figure 26: Forward Scheduling

If the result of backward scheduling means that the delivery date required by the customer cannot be confirmed, the system generally continues scheduling using forward scheduling. The earliest date on which the material is available in the warehouse is the new material availability date. This is the starting point for new delivery scheduling. Forward scheduling takes into consideration the time parallels of the work flows for transportation planning and picking/packing of materials. The longer of these two periods is relevant for scheduling. The selection date of the outbound delivery is the earlier of the material availability or the transportation planning dates.

Figure 27: Periodicity of the ATP Check

The ATP check in SAP ECC is accurate to the day. The day begins at 00:00 and ends at 00:00 in the time zone of the plant (local time) in which the ATP check takes place. The exact times (hour, minute, and second) of the planned requirements and planned receipt elements are not taken into account. The relevant elements are cumulated for each day and evaluated at the start of the day. As a result, all receipts are technically available at the start of the day, although they may actually be available only later in the day. Occasionally this leads to shortages. Note: SAP SCM APO can be adjusted to meet the customer’s requirements:

2009

•

Separate definition of receipt and issue buckets (move receipts)

•

Daytime availability check (= several buckets per day)

•

Evaluation logic of the ATP time series (bucket logic: conservative, totally conservative, and progressive)

•

Bucket limits can be managed in UTC or in summer time for the local time zone in the respective location.

SCM671

ATP Check Taking into Account the Replenishment Lead Time The replenishment lead time is the time required to order or produce the requested material and to provide it in the company. In the “availability check control,” you specify whether the ATP check is to be carried out with or without the replenishment lead time.

Figure 28: Check Taking into Account the Replenishment Lead Time

ATP Check Including the Replenishment Lead Time Availability is checked only until the end of the replenishment lead time. If the material availability date for the item when calculated from the current date is outside the replenishment lead time, the item can always be confirmed. In this case, the system assumes that any required quantity can be confirmed up to the material availability date and considers the goods to be available. They can therefore be contractually promised to the customer. If the material availability date is within the replenishment lead time, checks are carried out on the basis of the ATP quantity. The requirement is confirmed at the latest at the end of the replenishment lead time. The availability check that uses the replenishment lead time only produces meaningful results if you plan in regular intervals. (For single and daily requirements, you should plan on a daily basis. For weekly requirements, you should plan on a weekly basis). The confirmed quantities are then compared with receipts. This is necessary because the delivery date of an order that was confirmed on the day before the replenishment lead time already lies within the replenishment lead time on the current day, and thus leads to a shortage. This shortage could then prevent the delivery from being created, for example. ATP Check Without the Replenishment Lead Time

28


2009

SCM671


If the replenishment lead time is not taken into account during the availability check, the system carries out an unrestricted availability check. Note: For an explanation of the different results for the end of the replenishment lead time on the Availability Control and Availability Overview screens, see SAP Note 100291.

Figure 29: Calculating the Replenishment Lead Time

The replenishment lead time is the time required to procure or produce the material in full, that is, using all BOM levels. The system calculates the replenishment lead time using specific times that you define in the material master record and in Customizing. Depending on the procurement type, it can be calculated from different time periods. So that the replenishment lead time can be calculated correctly, you must enter the necessary times in the material master record and in Customizing. For materials produced in house, the following options are available. If the Total RLT field (MRP 3 View) is maintained, the time maintained in this field is used for the availability check. If the Total RLT field is not maintained, the system reads the in-house production time (MRP 2 view) and, if available, the goods receipt processing time (MRP 2 view) and interprets the total of these two times as the replenishment lead time for the availability check. For materials procured externally, it is not useful to maintain the Total RLT field. For external procurement, the total of the purchase processing time (Customizing: Materials Management → Purchasing → Purchase Requisition → Processing

2009


29


SCM671

Time), planned delivery time (MRP 2 view), and goods receipt processing time (MRP 2 view) is always interpreted as the replenishment lead time for the availability check. Note: All times are maintained as working days, with the exception of the planned delivery time, which is maintained in calendar days.

Concept of the Shortage Check

Figure 30: Shortage Check

Checking availability without taking into account the cumulated, confirmed quantity or requirement quantity (shortage check) may lead to overconfirmation. Based on the material availability date of the sales order in the past, the system checks whether there are receipt elements with an ATP quantity that is still free. If there is a planned receipt based on the material availability date of the sales order in the past, it is used to confirm the order requirement. If the planned receipt is then postponed to any date after the confirmation date, the sales order confirmation is retained even though there is not enough stock to cover the requirement. This is because changing the receipt does not automatically change the order. A new order created in this situation might also be confirmed because of the postponed receipt and thus lead to an overconfirmation. To correct the overconfirmation, you can execute a planning run, reschedule, or process a backorder. Since these functions require a lot of time, it is possible that orders whose entry dates indicate that they cannot be delivered are actually delivered. The shortage check prevents the scenario described above from occurring since when it is active, the system not only confirms past receipt elements on the basis of the available ATP quantity, but also checks whether the total requirements and

30


2009

SCM671


confirmations exceed the total stock and receipt elements. If confirming a new requirement means that the total number of requirements or confirmations in the system exceeds the stock and receipt elements, no confirmation can be made as part of the ATP check. In our example, the second order cannot be confirmed.

Figure 31: Activating the Shortage Check

You can activate the shortage check in Customizing for the checking group. The following options are available.

2009

•

No shortage check

•

Check taking into account the cumulated, confirmed quantities: When calculating the cumulated ATP quantity, the system takes into account the total of all previously confirmed quantities. This means that new sales orders can be confirmed only if the total receipts exceed the confirmed quantities. We recommend that you work with cumulated requirement quantities when you create sales orders (checking group, field Accumul. parameter 2 or 3).

•

Check taking into account the cumulated requirement quantities: When calculating the cumulated ATP quantity, the system takes into account the total of all requirement quantities open to date. This means that new sales orders can be confirmed only if the total receipts exceed the total requirement quantities. We recommend that you work with cumulated, confirmed quantities when you change sales orders (checking group, field Accumul. parameters 1 and 3).

•

In addition, an information message can be activated to inform the user about the shortage situation (checking group, field Response, parameter 1).


31


SCM671

Figure 32: Digression: Lock Logic

So that the results of the availability check are consistent, a material has to be locked for other users or checks during the availability check. There are two different lock concepts: Material block: In the IMG activity Define Material Block for Other Users, you specify whether a material master record is blocked for other users during the availability check for each checking group and call (order/delivery/material reservation). The block is set at material-plant level and remains until you save the sales document. Material block with quantity transfer: For performance reasons, it is useful to set the material block with quantity transfer only if multiple users often block the same material at the same time. If this is not the case in your organization, you can work with the standard lock logic at material-plant level. In Customizing, you can set the material block with quantity transfer in the IMG activity Define Checking Groups. If this lock is active, the material is only locked during the availability check when a sales document is created or changed. It is thereby possible that several users can process the same material at the same time within different operations without blocking each other. During the availability check, the material used is locked exclusively in the current plant in the same way as the standard lock. If another user attempts to process the locked material in the corresponding plant while the availability check is being carried out, the system waits for one second before making five attempts to lock the material exclusively for the second operation. If all five attempts fail, the check is canceled and the operation remains unconfirmed. To confirm the operation, the user must then call the availability check again. Once the check is complete, the confirmed quantities are locked, although not exclusively. The material block is reset. The non-exclusive quantity block then informs users processing other operations about the reserved quantities of the respective material that are currently in process in the selected plant. Once

32


2009

SCM671


processing is complete, the lock entries are reset. If the processed operation has been saved, the lock entries are reset only once the corresponding changes have been made to the database. Note: If both lock options are active, the lock with the quantity transfer takes priority. During manual backorder processing, a material with a quantity lock is locked exclusively so that the availability of this material cannot be checked during this time.

Business Example Configure the Customizing settings for the availability check. Learn how to activate the availability check and select the check method for the requirement class, schedule line category, and delivery item category. Analyze the determination of the requirement class in conjunction with the sales documents.

Task 1: Check the activation of the ATP check in Sales and Distribution. The availability check must be activated in the required method and for the relevant requirements class. For sales documents, the availability check must also be activated in the relevant schedule line categories. If an ATP check is intended for each delivery item, the availability check must not be deactivated for the relevant delivery item categories. In addition, the ATP check must not be deactivated for the checking group defined in the material master of the material to be checked. 1.

Task 2: It is essential that the availability check be activated in the required method and for the relevant requirements class. Therefore, use the options for determining the requirements classes in Customizing. 1.

Which two strategies does the system provide to determine the requirements type and therefore for requirements class? Answer: The requirements type/class can be derived based on the material (relevant fields: Strategy Group, MRP Group, and possibly Material Type). However, there are also business transactions that require the requirements type to be determined based on a transaction. Therefore, the requirements type/class can also be determined based on the order item category together with the MRP type of the material, or solely with the order item category.

2.

Which strategy has been used to determine the requirements type/class in the order item in the order from exercise 1, task 1 (order number: ## order 1)? Remember: Material T-AC1## was sold from plant 1200 Dresden. The order item was checked with item category TAN. Before the “determination strategy” of the requirements type/class is checked, determine the MRP type of material T-AC1## in plant 1200 Dresden.

Task 2: Define a new checking group. Configure a special “availability check control”. Define a new check scope for the ATP check of orders and deliveries. Decide the check level of the ATP check. 1.

To carry out the ATP check for material T-AC2## in plant 1200, you require a particular check control. You therefore create a new checking group ##+50. Since checking group ##+50 has no different requirements to checking group 02, you can use checking group 02 as a template.

2.

Now define a new “availability check control” for the “new” checking group 50+## to process sales and delivery documents. Use the “availability check control” checking group/check rule 02/A and 02/B as a template.

Since you are displaying the “Availability Overview” from order processing, the order is displayed on the material availability date as a “simulated requirement” in the amount of 200 pieces. On the material availability date of the requirement, a “cumulated ATP quantity” of only 150 meters is available. This “cumulated ATP quantity” results from the plant stock of the material. As a result, a maximum of 150 pieces can be confirmed on the requested date. However, there is a purchase order with a delivery date in approximately one month for 200 pieces of material T-AC2## for plant 1200. As a result, the “cumulated ATP quantity” as of the planned delivery date of the purchase order is 350 pieces. Therefore, up to 350 pieces can be confirmed after the planned receipt.

Exercise 4: Shortage Check Exercise Objectives After completing this exercise, you will be able to: • Understand the shortage check concept • Activate the shortage check

Business Example To avoid shortages, you want to include cumulated requirements and confirmed cumulated requirements when you carry out the ATP check.

Task: Now process the shortage check. You will first trigger a shortage situation and then create an order. Because you have not activated the shortage check yet, you will receive a confirmation in the sales order that is NOT realistic. Once you have activated the shortage check in Customizing, the system recognizes the shortage when you create an order and cannot confirm it. 1.

Now process the shortage check. To do so, first undo the changes that you made to the “availability check control” for test purposes.

Lesson: ATP Check in Manufacturing

Lesson: ATP Check in Manufacturing Lesson Overview This lesson covers the availability check for material components as part of production orders. It will present the concept of component availability, configuration options, and how to interpret the results.

Lesson Objectives After completing this lesson, you will be able to: • •

Explain how the availability check for material components is carried out and controlled on the basis of the ATP quantity Interpret the results of the availability check

Business Example Before you release a production order, you must ensure that all necessary resources are available for production. In production orders, you can check the availability of material components.

ATP Check in Shop Floor Control

Figure 33: ATP Check in the Production Order

Before you start to process a production order, you can check whether the material components assigned to the production order are or will be available on the calculated requirement date.

2009


103


SCM671

Availability checks can be started manually or automatically. An automatic availability check can be carried out both when you create and when you release an order. In addition, availability can be checked automatically when you save the order. In the Customizing settings, you specify whether an automatic check is to be carried out for each production order type and plant. A manual availability check can be carried out at any time. You can check the availability of materials for the entire order or for individual material components. The single check can be carried out in the component overview, the missing parts overview, and the missing parts list. With mass processing of production orders, you can check the availability of materials for multiple orders at the same time. In this collective availability check, the respective orders are always checked in full. If material components are not available on the requirement dates, the production order is assigned the status “Missing Material.” The unavailable components are assigned the status “Missing Part.” In addition, the quantity available on the requirement date is compared to the requirement quantity and a “confirmation date” is calculated for the complete requirement quantity. Note: Availability of material components can also be checked in the SAP system as part of requirements planning in the planned order. When doing so, you can check the availability of a planned order or check the collective availability of multiple planned orders at the same time. When you convert planned orders to production orders, you can use the availability situation of the planned orders as a selection criterion.

104


2009

SCM671


Configuring the ATP Check for the Production Order

Figure 34: Customizing for the ATP Check for Production Orders

In the “Define Checking Control” Customizing table, you can define the checking control of the production orders as part of the availability check, depending on the operation (1 = create production order and 2 = release production order), the type of production order, and the plant. In particular, you decide which availability check method you want to use to check component availability. Availability can be checked on the basis of the ATP quantity or planned independent requirements. If you use the ATP method for the availability check, assign the checking rule in this table. The checking rule, together with the checking group from the material master of the component, determines the scope of the check (ATP quantity calculation and check with or without the replenishment lead time). In addition, you specify for each operation in the checking control whether availability is to be checked automatically. For the “create” operation, you can also specify whether a planned order can be converted to a production order in collective conversion if there is a shortage of material. For the “release” operation, you can specify whether a production order can be released even though there is a shortage of material.

2009


105


SCM671

You also specify here whether availability should be checked automatically when you save a production order after having made a relevant change. Note: The checking rule for the availability check of planned orders is defined for each plant when the plant parameters are maintained.

Figure 35: Partial vs Full Confirmation Logic

In the production scheduling profile, you decide whether the ATP check is to be carried out in the production order according to full or partial confirmation logic. You can assign a production scheduling profile to a material (work scheduling screen in the material master record) or to the production scheduler (Customizing). The assignment to the material takes priority. The production scheduling profile is copied to the production order when the order is created. Full confirmation logic: In general, the system attempts to confirm the entire requirement quantity of a component if the ATP quantity allows. When full confirmation logic is used, all components are therefore confirmed according to their availability. Partial confirmation logic: If you want to make sure that only the quantities required in production are confirmed, you can use a partial quantity confirmation. When a partial quantity confirmation is used, all components are confirmed in relation to their quantity. All of the checked components then receive a confirmed quantity in the amount of the component with the lowest, relative confirmed quantity (confirmation factor).

SCM671


Interpreting the Results of the Availability Check

Figure 36: Evaluating the Results of the ATP Check

The following locations provide information about the result of the availability check: •

Availability log: This contains the result of the check (that is, whether all components are available), a list of missing parts, and a list of reservations that could not be checked (for example, because the material master data was not maintained). The log is not saved if you leave order processing.

•

Missing parts list: This lists missing parts, reservations that could not be checked (for example, because material master data was not maintained), all checked components, and the date on which other components are available. The missing parts list is not saved if you leave order processing.

•

Missing parts overview: This contains a list of missing parts, enables you to process them (for example, by changing the requirement quantity or issue storage location), and provides the date on which all components are available. The missing parts overview always displays the results of the latest availability check, regardless of whether you have left order processing in the meantime.

Lesson: ATP Check in Materials Management Lesson Overview This lesson introduces the use of the ATP check in Materials Management. When you work with stock transport orders, it may be useful to check the availability in the delivery plant. The ATP check can also be used for material reservations and stock postings. This lesson presents the checking processes. You will also learn how to configure the underlying Customizing settings and interpret the results of the availability checks.

Lesson Objectives After completing this lesson, you will be able to: • • •

Check availability based on the ATP quantity for stock transport requisitions, stock transport orders, and replenishment deliveries Check availability on the basis of the ATP quantity for material reservations and stock postings Interpret the results of the availability check

Business Example As part of plant-to-plant stock transfers, material availability in the delivery plant has to be checked on the basis of the stock transport order, or even on the basis of the stock transport requisition. It may also be useful to check the material availability for material reservations and stock postings. You want to use the ATP check for these checks.

Lesson: ATP Check in Materials Management

ATP Check as Part of Stock Transfers

Figure 37: Availability Checks as Part of Stock Transfers

When stock is transferred between two plants, it is useful to check the availability of the materials in the delivery plant and reserve them for the receiving plant when you create the stock transport order. An additional availability check can also be carried out when the outbound delivery is created in the delivery plant. This is useful since the ATP quantity may have changed in the time between creating the stock transport order and creating the outbound delivery. If required, you can also check the availability in the delivery plant when the purchase requisition is created. To do so however, you must create a stock transport requisition. In other words, the items in the purchase requisitions must have item category U (stock transfer) and the delivery plant has to be specified for each item.

2009


133


SCM671

Figure 38: Configuring the ATP Check for Stock Transport Orders

The availability check for stock transport orders must be defined for the material and configured in the Customizing settings. To be specific, this means that a checking group must be entered for the delivery plant in the material master, and that in Customizing, a checking rule must be assigned to the purchasing document type of the stock transport order (in the standard system, this is document type UB) in the delivery plant. For this combination of checking group and checking rule, the necessary check control or scope of check must be defined. If this is the case, the availability of the stock transport item is checked on the material availability date of the item. If the check is successful, it runs unnoticed. If the check is not successful, the system response is dependent on Customizing for the “availability check rule.” In general, the check generates a warning message or log entry. In addition, the system can select the delivery proposal independently based on the Customizing setting of the “availability check rule,” or it can branch to a user screen where the user chooses the appropriate delivery proposal. The result of the availability check is documented in the item details on the Delivery Schedule tab page in the form of one or more schedule lines. Note: SAP Note 885177 “Stock Transfer in Purchasing: New Schedule Line Purchasing” describes the different options for displaying the result of the availability check in the stock transport order. Requirements from stock transport orders can be revised as part of back order processing or rescheduling.

134


2009

SCM671


Figure 39: Configuring the ATP Check for Replenishment Deliveries

If the stock transfer is processed on the basis of an outbound delivery, another ATP check can be carried out when the outbound delivery is created. The system determines the checking control necessary for this using the checking group of the material and the checking rule of the delivery document. In the standard system, the assignment of the checking rule to the delivery is hard-coded. For availability of the outbound delivery item to be checked, the availability check must be active for the outbound delivery item type.

2009


135


SCM671

Figure 40: ATP Check as Part of the Stock Transport Requisition

If you want to check availability when you create the stock transport requisition, a check rule is assigned in Customizing for the purchasing document type used to control purchase requisitions, depending on the delivery plant. Together with the checking group of the material, this determines how the availability check is processed. The ATP check is controlled in the same way as the availability check in Sales and Distribution.

Dynamic Availability Check in Relation to Reservations and Goods Movements In Customizing, you can activate the dynamic availability check for creating reservations and goods movements. It is then carried out in addition to the hard-coded, static availability check. Static availability check The static availability check is carried out when the goods issue is posted and refers to this date. During the check, only the stocks that are currently available are taken into account – not the confirmed stock! The static availability check is programmed and cannot be changed in Customizing. Dynamic availability check The dynamic availability check refers to the requirement date. All receipts and issues are included as defined by the scope of the check. You can also configure the dynamic availability check to include the replenishment lead time. For example, there is a requirement in four weeks that it is not currently covered by the

136


2009

SCM671


existing stock. However, since the replenishment lead time is just one week, the requirement can be confirmed. The dynamic availability check must be activated based on the material and the movement type or transaction code.

Figure 41: Configuring the Dynamic Availability Check

In the material master record, a checking group must be entered for the availability check (in the standard system, on the MRP 3 or Sales: General/Plant Data tab page). For the goods receipt, goods issue/stock transfer, and reservation operations, set the indicator for the dynamic availability check for each relevant movement type. Examine which checking rules you want to use for which operations. Then assign the checking rules to the transactions for which the dynamic availability check is to be carried out. Depending on the checking rule and group, you then specify which elements (stocks, receipts, and issues) are to be included in the dynamic availability check, and whether the replenishment lead time should also be taken into account. Note: When you post a goods issue with transaction MIGO, transaction MIGO_GI is executed in the background. You must therefore enter the checking rules for goods receipts for transaction MIGO_GI.

Exercise 6: ATP Check in Materials Management Exercise Objectives After completing this exercise, you will be able to: • Configure the ATP check for stock transfers, material reservations, and goods issue postings • Interpret the results of the ATP check in Materials Management

Business Example To provide consistent and reliable supplier confirmations that correspond to Sales and Distribution, you want to use the ATP check for plant-to-plant stock transfers. When you create the stock transport order, availability is to be checked in the supplying plant. The stock transfer requirement is also to be “reserved” in the supplying plant. In addition, the stock transport order is to be included in the ATP quantity calculation in the receiving plant as a planned receipt. When you enter material reservations, you also want to include sales and stock transfer requirements that have already been confirmed, or you want to include confirmed material reservations in the ATP checks in Sales and Distribution. For goods movement postings, you want to use the dynamic availability check along with the static availability check.

Unit 2: Availability Check Against Product Allocations

SCM671

Lesson: Availability Check Against Product Allocations Lesson Overview The quantities that your company can provide are lower than market demand. So that your first customers do not exhaust your entire stock, you define product allocations for customers or customer groups.


Explain the concept of the availability check against product allocations Configure the availability check against product allocations Interpret the results of the availability check against product allocations

Business Example Using product allocations, you can assign products for specific customers, regions, or other attributes depending on the period. For example, this can prevent the entire available quantity of a product in short supply from being allocated to the first customer, meaning that it would no longer be possible to confirm subsequent sales orders or that they would be confirmed far too late.

Concept of Product Allocation

Figure 42: Concept of Product Allocation

The product allocation function allows you to manage the supply of scarce products to customers so that each customer receives at most the allocated amount. You can maintain allocations for customer groups, sales organizations, and so on, as well as for individual customers.

166


2009

SCM671

Lesson: Availability Check Against Product Allocations

The ATP check can be combined with the product allocation check. The product allocation control process permits the user to manage allocations at a specific material level and at various product group levels. Product allocation encompasses internal allocations to sales organizations and distribution channels, as well as external customer groups and specific customers. The system also supports the fact that there are different phases of allocation control during the overall constraint period.

Figure 43: Check Against Product Allocations

Incoming requirements are checked against the “available” product allocation quantity. The relevant product allocation is calculated on the basis of the order attributes. If there is no “available” product allocation quantity in the period in which the material availability date falls, the requirement cannot be confirmed or cannot be confirmed as requested.

2009


167


SCM671

Figure 44: Creating an Order with ATP Check and Product Allocation

A product allocation check can act as a secondary check against the quantity requested in the sales order. First, an ATP check can be carried out against stocks and receipts, possibly resulting in a lower confirmed quantity due to insufficient stock. This confirmed quantity can then be checked against the product allocation, possibly resulting in a further reduction of the confirmed quantity. Product allocation encompasses allocations for all sales order attributes, including sales organizations and distribution channels, external customer groups, and specific customers. For other attributes, you have to use the user exit INCLUDE Fv45vfzy user exit_quota_key_va (transaction SE38).

168


2009

SCM671


Figure 45: Activating Product Allocation

So that you can use the product allocation check, this availability check method must be active for the relevant requirement classes and schedule line category. In Customizing (Availability Check Against Product Allocation → Define Flow According to Requirement Category and Process Flow for Each Schedule Line Category), activate product allocation for the relevant requirement category and schedule line category.

Figure 46: Elements of Product Allocation

2009


169


SCM671

To use product allocations, you must complete the following steps: •

In Customizing (Sales and Distribution → Basic Functions → Availability Check and Transfer of Requirements → Availability Check → Availability Check Against Product Allocation → Maintain Procedure and Define Object), define a product allocation procedure and object (reason for product allocation).

•

In Customizing (Availability Check Against Product Allocation → Specify Hierarchy), link the procedure to an information structure.

•

In Customizing (Availability Check Against Product Allocation → Control Product Allocation), assign your objects to a procedure.

•

Maintain the procedure in the material master records (basic data) of the materials you want to allocate.

•

Maintain the planning hierarchy and updating rules for your allocation info structure.

Figure 47: Function of the Product Allocation Objects

The system includes the different phases of product allocation control in the overall constraint period. You can assign several product allocation objects to the product allocation procedure. Each object has its own validity period. The system determines the relevant object on the basis of the updating date for the key figure of the info structure. It then uses the object to determine the corresponding planning hierarchy, which contains product allocations. Objects are always valid from the end date of the preceding object. To deactivate product allocation for a certain period, define a dummy object and set it to inactive. The system allows only three update dates: delivery date, material availability date, and planned goods issue date.

170


2009

SCM671


You can maintain time-dependent conversion factors for your allocation objects in the IMG activity Control Product Allocation.

Figure 48: Information Structure

Information structure S140 is configured accordingly for product allocation. You can also create your own information structure. When you create your planning hierarchy, assign the allocation objects to the highest level. Specify the proportional factors from which allocation percentages are derived for specific characteristic values. The allocation check is always performed at the detailed level of the hierarchy. In Customizing at Availability Check Against Product Allocation → Specify Hierarchy, you can enter a masking ID for each information structure. The masking ID stands for collective characteristics. Once you have entered the planning hierarchy, you can add collective characteristics to it. To do so, choose the IMG activity “Permit Collective Production Allocation in Info Structures”. This creates a default entry for the specified nodes in the hierarchy. Different masking IDs cannot be used for different procedures assigned to the same info structure. If an info structure has been assigned several times, assignment is permitted with or without masking.

2009


171


SCM671

Figure 49: Planning Table

The planning type for the standard info structure S140 is COMMIT. It contains predefined macros for product allocation. Note: You must plan allocation quantities in version 000 (actual data).

Figure 50: Discrete Product Allocation

The system provides two product allocation procedures: •

Discrete product allocation

•

Cumulative product allocation

If you do not select the ATP Consumption indicator in the IMG activity “Maintain Procedure,” the system uses the product allocation procedure from Release 3.0F (discrete ATP check).

172


2009

SCM671


Using this method, the system offsets the quantity confirmed in the sales document against the product allocation quantity. It uses only the product allocation quantities from current and future periods (unused product allocation quantities from past periods are not taken into account). If you use the discrete method, you cannot use the following product allocation functions: •

Consumption periods

•

Product allocation steps

Figure 51: Cumulative Product Allocation

If you set the ATP Consumption indicator in the IMG activity “Maintain Procedure,” the system uses the cumulative product allocation procedure. This procedure contains check logic that corresponds to the cumulative ATP logic. When the available product allocation quantities are calculated for the current period, the system takes into account unused product allocation quantities from previous periods. In cumulative product allocation, the following functions are available:

2009

•

Allocation steps: Here you can define several product allocation steps with different info structures.

•

Consumption periods: Here you define a number of past and future periods to be used as the valid consumption period.


173


SCM671

Figure 52: Consumption Periods

In cumulative product allocation, you can restrict the number of periods under consideration by entering a consumption period. The number of past periods identifies the number of periods before the product allocation date in the order that can be used to calculate unused product allocations. The unused product allocation quantities of these past periods are then cumulated before the product allocation for the current period is checked. The number of future periods identifies the number of periods after the product allocation date in the order that can be used to calculate future product allocations. If the requested quantity is not confirmed within the future periods, it remains unconfirmed.

A confirmation of 400 cartons is not possible. On the required date, the system can confirm 100 cartons. In addition, the availability check proposes three partial deliveries of 100 cartons each. Each partial delivery takes place at the start of the three months after the required date. Hint: If the requested delivery date for the order item is in the next month (as seen from current date or creation date), the product allocation will confirm 200 cartons for the requested delivery date. In this case, the delivery proposal consists of two partial deliveries: 200 cartons on the requested delivery date and 100 cartons in the following month.

Unit 3: Availability Check Against Planned Independent Requirements

SCM671

Lesson: Availability Check Against Planning in Sales and Distribution Processing Lesson Overview You execute a check against planning if you want to know whether enough planned independent requirements are available for the incoming sales orders. The check against planning is carried out against a planned independent requirement for an unknown market (usually one that is not customer-specific).


Explain the concept of the availability check against planning Configure the availability check against planning for Sales and Distribution processing Interpret the results of the availability check against planning

Business Example The check against planning is carried out against a planned independent requirement created for an unknown market (usually one that is not customer-specific). The planned independent requirement results from demand program management and is used for non-order-specific planning of expected future sales quantities. As a team member, you are responsible for configuring the Customizing settings and maintaining the data for the availability check against planning.

Concept of the Check Against Planning When planning for expected sales orders, you determine which order quantities are anticipated for product groups and salable products in a specific period. In Demand Management, planned independent requirements are created for a specific period for expected order quantities. Once the order has been received, the relevant consumption quantity of materials whose requirements are consumed against the production program are transferred to materials planning as part of the availability check against planning for the order quantities. Material planning then reduces the associated independent requirements level by level. If a planned independent requirement is not available for customer requirements, the requirement cannot be confirmed since (to date) production or procurement is not scheduled. To understand the concept of the availability check against planning, we must consider the planning strategies. A good example is strategy 52 (planning without final assembly/without make-to-order production). In this planning strategy, future sales figures are forecasted for the finished product in demand planning.

190


2009

SCM671

Lesson: Availability Check Against Planning in Sales and Distribution Processing

A production plan is derived from these, and in turn, planned independent requirements for the finished product are generated. In the planning run, planned orders are then compared to these planned independent requirements as receipt elements. However, the planned orders have the order type VP and therefore cannot be converted to purchase orders or production orders. As a result, the finished product is neither procured nor produced. However, dependent requirements and corresponding receipt elements are generated in the planning run for the components of this finished product. These planned orders can be converted, thus achieving the main goal of this strategy: Components are procured even without sales orders on the basis of demand management. If a sales order is created for the finished product in this scenario, an ATP check always fails. There is no stock and no receipt elements (for example, production orders or purchase orders) for the finished product. Therefore, a check is carried out against planning in this context. The system checks whether there is a planned independent requirement for the finished product in the consumption period and for the relevant consumption mode; if so, the customer requirement can be confirmed since enough components will be procured to manufacture the finished product before it is sold. In the next planning run, the customer requirement is consumed against the planned independent requirement, and a planned order that can be converted is generated for the customer requirement quantity. As a result, production of the finished product is triggered. Besides planning strategy 52, the check against planning is also used in planning strategies: 50 (planning without final assembly/with MTO), 60 (planning with planning material/with MTO), 63 (planning with planning material/without MTO), and 74 (planning without final assembly at assembly level). To summarize the check against planning:

2009

•

Only planned independent requirements are taken into account, meaning that MRP elements such as stock are not considered.

•

Customizing settings must be configured for the checking rule.

•

The Avail. Check field in the material master record is used only to define the transfer of requirements.


191


SCM671

Configuring the Check Against Planning

Figure 53: Activating the Check Against Planning

The requirements class determines the decision to use the checking method “check against planning”. Before the check against planning can be carried out, the Sales and Distribution applications in question must transfer a requirement. The availability check parameter must not be active in the relevant requirement class. Otherwise, the system checks against the ATP quantity and not against planning. The Avail. Check (check group) field in the material master records must be maintained. This specifies the requirements transfer (daily requirement or individual requirement).

192

SCM671


Figure 54: Consumption of Customer Requirement Against Planned Independent Requirement

In the strategy, you specify which planning requirements are to be consumed against which customer requirements, if at all. You assign a requirements type for planning to a requirements type for customer requirements by setting a consumption or allocation indicator. Requirements can be consumed and offset against each other only if they are defined with the requirement type assigned in the strategy and if they have the same consumption or allocation indicator. Planned independent requirements must be properly consumed and reduced before availability can be checked against planning.

Figure 55: Consumption Logic

2009


193


SCM671

In addition, the consumption mode and period for the planning check and consumption must be defined. This can be done in the MRP group in Customizing or in the material master record. The settings in the material master record take precedence over those for the MRP group. Using the consumption mode, you specify whether customer requirements are to be consumed against planned independent requirements. If so, you also specify the direction in which this is to occur, starting from the requirement date that corresponds to the material availability date of the order item in the sales order items. You have the following options: •

No consumption against planning

•

Backward consumption only; Consumption begins on the requirements date moving backwards only within the corresponding consumption period.

•

Forward consumption only; Consumption begins on the requirements date moving forwards only within the corresponding consumption period.

•

Backward/forward consumption; Consumption begins on the requirements date moving first backwards and then (if independent requirements before the requirements date cannot be assigned) forwards within the corresponding consumption period.

•

Forward/backward consumption; Consumption begins on the requirements date moving first forwards and then (if independent requirements after the requirements date cannot be assigned) backwards within the corresponding consumption period.

You can specify a consumption period that determines the consumption horizon for both backward and forward consumption. If backward/forward consumption or forward/backward consumption are both active, the system also takes into account both periods. The customer requirement is consumed using the planned independent requirement from the closest point in time either before or after the sales order date. If a customer requirement cannot be consumed in full by the nearest planning requirement, it is assigned to further planning requirements either in the future or in the past. To do so, the system uses the consumption periods that are maintained in the material master or in the Customizing settings for demand management (see above). For forwards and backwards consumption, the consumption periods specify the time interval within which customer requirements are consumed with planned independent requirements. Customer requirements outside the consumption period are not consumed.

194


2009

SCM671


Customer requirements are assigned to planned independent requirements dynamically. In other words, if sales orders or planning are rescheduled, the assignment is deleted and redefined. Note: If no consumption periods are maintained, requirements can be consumed by each other only if they are scheduled on the same day.

Which strategy has been used to determine the requirements type/class in the order item of the order from task 1? Hint: Remember: Material T-AC5## was sold from plant 1200 Dresden. The order item was managed with item category TAN. The MRP type of material T-AC5## in plant 1200 Dresden is PD.

Hint: Requirements class 049 is assigned to requirements type KSVS (see above). As a result, this planning strategy was relevant for “your” order.

Task 3: Now maintain planned independent requirements for material T-AC5## in plant 1200 Dresden. Then check the consumption logic of the customer requirements with the planned independent requirements for this material in plant Dresden. 1.

Maintain the following planned independent requirements for material T-AC5## in plant 1200. Note: In reality, planned independent requirements are created “automatically” as a result of demand management. In this exercise however, the focus is on the availability check against planned independent requirements and we therefore do not discuss this method of creating planned independent requirements. In the exercise, the planned independent requirements are created manually.

Unit 4: Backorder Processing and Rescheduling

SCM671

Lesson: Backorder Processing and Rescheduling Lesson Overview This lesson covers backorder processing and rescheduling. This essentially involves reprocessing requirements that have already been entered to “improve” the confirmation situation by allocating additional ATP quantities or reallocating them.

Lesson Objectives After completing this lesson, you will be able to: • • • •

Explain the need for processing backorders and rescheduling Describe the situations in which you use backorder processing and rescheduling Process backorders and reschedule, as well as analyze the results Configure the necessary Customizing settings

Business Example The demand for your products was greater than you expected. Not all customer requirements and stock transport requirements could be confirmed “as requested.” Furthermore, there are procurement bottlenecks. Vendors have informed you that they are not able to deliver the purchase orders as agreed. In this situation, you must now decide which requirements have the highest priority so that you can deliver these (if possible) as requested. Fulfilling other requirements may have to be postponed.

Using Rescheduling and Backorder Processing You use rescheduling to obtain confirmations for sales documents, stock transport orders, stock transport scheduling agreements, and stock transport requisitions that have already been entered, and to reprocess quantities and dates that have already been confirmed. Backorder processing also allows you to process dependent reservations of production orders. The aim is to improve the confirmation situation for these or some of these documents. With rescheduling and backorder processing, you can allocate additional stocks and planned receipts to the documents, or reallocate existing stocks and planned receipts among existing documents. In detail, you can use rescheduling to: • • •

222

Breach the “first-come, first-served” principle and allocate the ATP quantity according to other priorities Allocate additional quantities or planned receipts to existing documents Resolve shortage situations


2009

SCM671

Lesson: Backorder Processing and Rescheduling

Figure 56: Example: Rescheduling/Backorder Processing (1)

The example from an ATP check shows a possible application scenario for rescheduling and backorder processing. At the time the first order is entered, the entire ATP quantity of the first receipt is available. The requirement can therefore be confirmed on the basis of this ATP check.


2009


223


SCM671

The second order, which has a required delivery date before that of the first order and may therefore have a higher delivery priority, cannot be confirmed since there is no available ATP quantity.


Depending on the planning strategy, a requirement is usually transferred to materials planning. Materials planning then recognizes the shortage situation and plans a second receipt element.

224


2009

SCM671



Without backorder processing or rescheduling, the confirmation situation does not change for the requirements entered. Or in other words: Once a requirement has been saved, it cannot be used to check the ATP situation so that it can be confirmed. The user must process the backorder or start rescheduling. In this example, once backorder processing or rescheduling is complete, both orders can be confirmed as requested.

Backorder Processing SAP ERP provides two ways in which you can reprocess entered requirements:

2009

•

(Manual) backorder processing

•

Rescheduling


225


SCM671

Figure 60: (Manual) Backorder Processing

When you process backorders, you select all relevant documents (defined by the check scope) for a combination of material and plant. The Backorder Processing: Overview screen provides an overview of the ATP situation. This allows you to allocate the existing ATP quantity manually for sales documents, stock transport orders, stock transport scheduling agreements, stock transport purchase requisitions, and dependent reservations. You can also reduce the confirmed quantity for these documents, which increases the ATP quantity so that it can be reallocated.

226


2009

SCM671


Figure 61: Rescheduling

Backorder processing can also be carried out “automatically” online or in the background. In this context, we speak about rescheduling. With rescheduling (program SDV03V02), all open sales document items for the selected combination(s) of material and plant are processed. If required, rescheduling also processes open items and schedule lines for stock transport orders, stock transport scheduling agreements, and items from stock transport requisitions for the selected combination(s) of material and plant. Note: Program SDV03V02 always selects all requirements of the selected material/plant combination(s). In other words, requirements with fixed quantities and dates are selected, as well as material reservations. However, these documents are not reprocessed and so their confirmation status remains the same. For stock transport documents, you can specify whether stock transport requisitions and scheduling agreements are to be processed at item or schedule line level. “Open” in this context means that (for example) the only documents to be processed are: undelivered orders, documents not marked for deletion, items from stock transport requisitions that are not marked as complete, and items from stock transport orders in which the quantity delivered and posted in the goods receipt differs from the quantity ordered.

2009


227


SCM671

The selected items and schedule lines are sorted according to the “priorities” on the selection screen (document category, delivery priority, date on which the item was entered, and for stock transport orders and scheduling agreements, possibly the delivery date of the earliest schedule line, document, and item number). They are then transferred to the availability check so that the ATP quantities of these documents can be reallocated with this priority. In terms of the priorities, 1 is the highest priority and 5 is the lowest. Stock transport requisitions are generally sorted after stock transport orders and scheduling agreements since they are less binding. This means, for example, that if sort criteria (such as the delivery date) are identical, a stock transport item is checked first and then the stock transport requisition item. If you set the Simulation indicator, the checked documents are not saved; only a results list is generated and saved. The availability check for the respective documents therefore responds as if it had been saved, meaning that the simulated list corresponds to the actual one.

Customizing Backorder Processing and Rescheduling

Figure 62: Configuring Backorder Processing and Rescheduling

The scope of check for checking rule “A” is generally used for rescheduling sales documents (exceptions include rush orders, for which checking rule “B” is used, and orders with project stock, for which checking rule AE is used). For stock transport documents, the check scope of the checking rule assigned to the respective stock transport document category in Customizing for purchasing applies. You must ensure that the scopes of the checks are consistent for both

228


2009

SCM671


stock transport documents and sales documents, and that they do not exclude one another since this would otherwise cause the check results to be incorrect. Example of an incorrect setting: In the check scope for checking rule “A,” release orders for stock transport orders and requisitions are checked, but not in the check scope of the checking rule for stock transport scheduling agreements. For (manual) backorder processing (transactions CO06 and V_RA), you can/must enter a proposal for the checking rule of backorder processing for each plant in Customizing. This proposal can then be copied or changed when you call backorder processing. The Customizing parameter “Rule for Transferring the Results of the Availability Check” allows you to specify how the SAP system responds when rescheduling results in an undesired availability situation: Should the system choose the option One-Time Delivery, Delivery Proposal, or Complete Delivery? This “rule” is defined individually for sales documents and stock transfer documents.

Exercise 9: Backorder Processing and Rescheduling Exercise Objectives After completing this exercise, you will be able to: • Name the application areas of backorder processing and rescheduling • Process backorders • Start rescheduling and evaluate the results

Business Example Not all of the requirements entered can be confirmed as required. In particular, sales orders that are received late cannot be confirmed or can be only partially confirmed due to a restricted ATP quantity. As part of backorder processing or rescheduling, you now want to breach the first-come, first-served principle and allocate a restricted ATP quantity on the basis of delivery priority.

Task 2: Manual Backorder Processing 1.

You decide that the sales order for Motorradmarkt Stuttgart must be delivered as soon as possible. To confirm this order, you use quantities that have been “reserved” for the first schedule line of the release order. However, the total confirmation of the release order must remain at 1000 pieces. You therefore use 100 pieces of T-AC6## that have been used/reserved for the sales order with delivery priority 3 to confirm the release requirement. Carry out the relevant (manual) backorder processing. Hint: Do not save the backorder processing. You still need this example for the rescheduling task.

Then reschedule the order again. To do so, use the processing parameters described in step 2 of this task. First reschedule the order in a simulation. Analyze the result of the rescheduling. _________________________________________________________ _________________________________________________________ _________________________________________________________ _________________________________________________________ _________________________________________________________ a)

The order with the Fix Qty/Date indicator is no longer included in the rescheduling. It retains its confirmations. The ATP quantity has been redistributed between the stock transport order and the Motorradmarkt order on the basis of the delivery priority. The order has a higher delivery priority and therefore is allocated the ATP quantity from the stock transport order. The stock transport order has been impaired. Instead of 1,000 pieces of T-AC6##, a total of only 900 pieces can now be confirmed for the stock transport order.

Lesson: Appendix

Calculating the ATP Quantity

Figure 63: Case Study: Initial Situation

The graphic shows the initial situation for the sample material in the availability check plant: •

The current plant stock is 100 pieces.

•

Expected receipts include two purchase orders: 50 pieces in 4 weeks and 60 pieces in 8 weeks.

•

Requirements that are already scheduled and that have to be taken into account include three sales orders of 100, 40, and 50 pieces in 2, 6, and 10 weeks respectively.

Using this as a basis, we will create an additional order of 10 or 20 pieces of the material in the following four case studies. Depending on the required delivery date and the material availability date, various confirmation statuses will arise.

2009


249

Unit 5: Appendix

SCM671

Figure 64: Case 1: Conformation on Required Delivery Date

In case 1, an order for 10 pieces is created. The material must be provided in 5 weeks so that the required delivery date can be met. The question is whether the required 10 pieces can be provided in 5 weeks based on the current stock situation and the planned issues and receipts.

250


2009

SCM671

Lesson: Appendix

Figure 65: Result for Case 1: Confirmation on Required Delivery Date

The availability check shows that the system can confirm the 10 pieces for the requested delivery date, without the other planned orders being endangered.

Figure 66: 2. Case 2: Confirmation for a Later Date

In case 2, the customer requires 20 pieces, not 10.

2009


251

Unit 5: Appendix

SCM671

The material should be provided in 3 weeks. The customer also requires a complete delivery. What is the earliest date on which the 20 pieces can be provided?

Figure 67: Result for Case 2: Confirmation for a Later Date

The order cannot be confirmed for the required delivery date. Due to the “complete delivery” agreement, the quantities cannot be divided. The 20 pieces can therefore be provided only after the second purchase order has been received. Based on the materials availability date, the system uses delivery scheduling (forward scheduling) to calculate the confirmation date for the delivery of 20 pieces.

252


2009

SCM671

Lesson: Appendix

Figure 68: 3. Case 3: Partial Deliveries

If the customer agrees, the required order quantity can be divided into several partial deliveries. In case 3, the initial situation is the same as cases 1 and 2. In case 3, however, the customer needs the goods as soon as possible and allows you to divide the delivery quantities into partial deliveries, if necessary. The new sales order with a requirements quantity of 20 pieces is entered; the required delivery date is in three weeks. When can the material be provided for partial deliveries and in what quantity?

2009


253

Unit 5: Appendix

SCM671

Figure 69: Result for Case 3: Partial Deliveries

The order cannot be confirmed for the required delivery date. However, the “partial deliveries permitted” agreement means that the quantity can be split up. You can confirm the 20 units for two later dates, each with 10 units.

Lesson: Appendix

Figure 70: 4. Case 4: Inclusion of the Replenishment Lead Time

In case 4, the system assumes that the material will be available at the end of the replenishment lead time by the latest. The replenishment lead time is an empirical value that can be entered in the material master and indicates the time usually required to procure this material. The availability check is only run until the end of the replenishment lead time. If the system checks availability using the replenishment lead time, you can provide 20 pieces on the requested date. If you check availability without including the replenishment lead time, however, the result is the same as case 2. You cannot make 20 pieces available until the date on which the last purchase order for 60 pieces arrives (receipt).

Collective Orders

Figure 74: Collective Orders in Production

Collective orders are the only way in which you can manage production orders on multiple levels. This is integrated in all components (SD, MM, and so on) of the SAP ECC system. For each BOM component whose material master contains the special procurement key 52, a separate suborder is created automatically (special

2009


257

Unit 5: Appendix

SCM671

procurement type: direct production). The special procurement key of the material master can be overridden using the explosion type field in the BOM item. All orders in the collective order have the same order type. Production versions are transferred from the leading order to the suborders. The lot size indicator (in the material master) is not taken into account when you open individual orders. Individual orders can be added or deleted. Each component in an order (whether or not it has special procurement key 52) can be made operational for an order. Other useful special procurement types (such as “production in an alternative plant”) can be combined with direct production (collective order).

Lesson: Appendix

Figure 76: Collective Orders – Availability Check

All orders in the network or subnetwork are always checked during the availability check. The missing parts overview lists all missing parts. You can make changes to the missing parts. The list is saved with the status of the last check. The missing parts list contains all missing parts and components that cannot be checked. This list is not saved.

Assembly Processing

Figure 77: Assembly Processing

The individual components for the final product have already been produced for make-to-order production with assembly production. You then only need to assemble the components according to the customer’s wishes. This means you need just a one-level bill of material explosion and you do not need to generate dependent requirements. This means that you do not need a planning run at this point for make-to-order production with assembly processing. You can create a production order directly from the sales order. When you do so, the availability of the production order components is checked. The system returns the confirmed quantity and delivery date from the production order to the schedule lines in the sales order. Any changes made to the confirmed schedule lines or the delivery date are immediately visible in the sales order and/or in the production order.

Lesson: Appendix

Subcontracting

Figure 78: Subcontracting

With subcontracting, your vendor (subcontractor) receives with components from which a product is manufactured. The end product is requested by your company through a purchase order. The components required by, and subsequently provided to, the subcontractor to manufacture the ordered product are listed in the purchase order. Materials can be provided in an LE delivery. The components can be determined by the system through a bill of material. You order the finished product in a subcontract order. The components that the vendor receives to manufacture the finished product are listed in the purchase order. To create this, you can use a BOM, which can also contain other components that the vendor provides. From the component overview of the purchase order, you can check the availability of components for the requirement date by choosing Component List → Component Availabil. The components are then delivered to the vendor and managed as part of vendor-based special stock O (= stock of material provided to vendor). The vendor may receive these components from you or from another business partner. If you dispatch the components to the subcontractor from your company, you can use the shipping activities. The vendor provides the agreed service and delivers the ordered material (the finished product). The consumption of the components is

2009


261

Unit 5: Appendix

automatically posted with the goods receipt posting. If the vendor informs you that fewer or more components were consumed than planned after you have posted the goods receipt, you have to change the stock (subsequent adjustment). The vendor provides an invoice for the services rendered and this is checked in invoice verification.
