Understanding SAP Event Management (SAP EM)
What is it and What can it do for you?

SAP Event Management “SAP Event Management is an application that supports control processes for managing events within and between companies. It consists of a set of integrated software functionality that supports five business processes: monitor, notify, simulate, control and measure supply chain activities.” AMR Research, January 2000
Why SAP EM? •Provides visibility on statuses, location, partners across processes •Manages sequence of expected events or milestones •Allows you the ability to “Manage by Exception” by handling unexpected events •Ensures events are measured against when they are expected to occur •Ensures that quantitative data is within the defined values •React to expected events that are not reported •Tight BW integration for reporting

SAP EM Terminology • Business Process Type (BPT) The Business Object or Process for which events are managed
1 BPT can have many AOTs E.g. Shipment, Production Order, Purchasing Process
• Application Object Type (AOT) Distinct business object or collection of business objects or part of a business object subject to SAP EM relevance or against which events can be reported
Should be chosen based on who’s viewing the object. Carriers => Shipments, Customers => Deliveries 1 AOT can have many EHs E.g. Container shipment, Procurement Process
• Application System (AS) Any mySAP system, R3 system, B2B, 3rd party or legacy system that holds Application Objects (as described above) that are managed on SAP EM
E.g. ECC, SCM, 4.6C, Java Application, Flex Application
• Event Management (EM) mySAP SCM component handling event management
Event Handlers • Event Handlers are of a certain Event Handler Type
What objects are to be managed? How do they relate to each other?
• Event Handler Types determine the behavior of an Event Handler at processing
time
Determines Rule Set to use – use – How to process inbound events related to the event handler Determines Expected Event Profile – Profile – Which events are required and where do they get mapped from Determines Status Attribute Profile – Profile – What Phases and Status Values can an event handler go through?
• For each event handler we store data
Expected Events, Unexpected Events, Event Messages Status attribute values Tracking IDs, Query IDs, Application Object ID Parameter values – values – Name value pairs – pairs – Control, Info and System Authorization Data Measurement Data
Event Handlers
To create an EH the system performs these steps:
In the Application System (AS)
Determines relevant AOTs
Extracts applicable Business Object Data to allow it to set up the EH
Checks status of all applicable EHs for the business object
Extracts parameter data for the EH
Posts parameters to SAP EM
Logs transaction status in application log
In SAP Event Management
Generalize parameter set for specific SAP EM view
Determine correct EH Type
Create / Update / Delete EHs
Events •2 types of events: Events that you expect to happen Milestones Events that actually happen •These can be broken down further: Regular event Early / Late event Unexpected Event Unreported event • Can be entered via: the web (WCL) XML -> XI IDoc RFC (SAP Systems preferred) BAPI RFD SAP EM directly (/SAPTRX/MI02)

Functional Elements of SAP EM • Application System (AS)
Execute data processing in Application system. E.g. ECC BAdIs
• Application Interface (AI)
Determine EM relevance; Extract data Basis Plug-in

SCM
ECC
• Control Channel (CC)
Generalize extracted EM data; Consolidate processes
• SAP Event Management (SAP EM)
React to Events / non-events
• Business Warehouse (BW) Supply data for analysis

Through customizing we can have a common interface from the ASs
All tables containing data that could be used in EM should be sent to the AI

Design Designing ing Quest Question ionss - AOT Answering these questions for your business process will help you define the business elements of the Application Object Type:
Under which condition does an Application Object need to be considered for EM? (Event ( Event Management Relevance) Where does planned event data come from? Where do info and control parameters come from? How are query and tracking IDs determined? What is the key that connects the Application Object and the Event Handler? (Application Object ID) From which tables in the application application system does the data come? (BPT, Main/Master Table) What is the corresponding SAP Event Manager?
Design Designing ing Ques Questio tions ns - EH Answering these questions for your business process will help you define the elements of the Event Handler:
What are the events you want to manage using the Event Manager? (Expected Events and Event Codes)
How do you identify your event handler? (Tracking/Query ID)
What additional information or data do you require? (Parameters)
What data do you need to get a quick overview of the status of an event handler? (Status) What, and under which conditions, does this event handler need to be created? (Event Handler Type and Condition) To build a complete business process, which event handler types should be grouped together? (Event Handler Set)

Lessons Learned • Extensive design work up-front Event handlers Event Messages BW reporting needs
• Go easy on Expected event modifications (Performance) Don’t do it unless absolutely necessary
• Keep your Event Handlers simple • Code your own BW extractor • Review Queues (SMQ1/2) and their performance Use custom code in BAdIs to enable parallel pa rallel queues
• Stick to standard WCL or Web Dynpro reporting • Code your rule sets very efficiently Don’t run rules unnecessarily – Use true rules Use function modules instead of check conditions
7 Key Points to Take Home SAP Event Management => track process status Don’t confuse workflow and SAP EM
1. 2.
3. 4. 5. 6. 7.
Workflow: Focused on pre-defined tasks performed by business objects or people SAP EM: Focused on Statusing and Events to determine de termine proactive and reactive actions
SAP EM is a stand alone utility. Track SAP and non-SAP events KPIs for performance across a process or parts of a process => SAP EM and BW Leverage the standard visibility scenarios given by SAP to jump start your implementat implementation ion SAP EM is extremely configurable and complex. complex . It is difficult for a part time resource to “pick it up” => full time resource Exception based management => SAP EM
