This guide helps to understand the configurations confi gurations required for IDoc scenarios with IDoc_AAE adapter type in PI 7.3/ 7.31 involving advanced adapter engine. Unlike other type of adapters, the Java IDoc adapter has dependencies on configurations in backend SAP systems and configurations in NWA apart from the configurations which have been maintained in communication channel with Adapter type IDoc_AAE. INTRODUCTION The new IDoc Adapter IDoc_AAE Adapter IDoc_AAE is is part of the advanced adapter engine and is a java implementation which does not use ABAP services. The configuration for IDoc_AAE for IDoc_AAE adapter adapter is different when compared to the IDoc Adapter (ABAP Stack). For configurations related IDoc Adapter in PI Dual Stack refer how-to guide How to Configure IDoc Adapters (NW7.0).

However this current document provides the details about the configurations required for using Java IDoc Adapter (IDoc_AAE) IDoc_AAE) and other important settings like creation of destinations, configuration of resource adapter in NWA which are required for IDoc related scenarios. The three different modes which are available for configuring communication channels with the IDoc_AAE Adapter type are: are: 1. Default (recommended) 2. Manual 3. From NWA

Note: The configurations shown here are from swing client and similar options are available if configurations are done via NWDS. In dual stack installation we can use either IDoc or IDoc_AAE adapters. The additional configurations in R/3 system related to creation of Partner Profiles (WE20), Ports (WE21) will not be discussed in detail as part of this guide. The configuration steps for each mode (Default, Manual and From NWA) in case of Sender and Receiver IDoc channels are mentioned separately below.

Preparation The developer should have necessary permissions to log-on to PI system, SOA Monitor and Configure Destination and Resource adapters in NWA. Required Business systems need to be imported in Integration directory of PI from SLD.

CONFIGURATION REQUIRED FOR SENDER CHANNEL WITH IDOC_AAE ADAPTER TYPE The goal of the sender configuration is to establish a technical connection from the R/3 system to the PI system for sending the IDOCs from the former into the latter. The connectivity is established using RFC technology. There are different RFC connections that are maintained on PI and the R/3 system. 

The PI system receiving the IDOC needs to query the sending R/3 system to understand the structure of the received IDOC. An RFC connection is created for this purpose on the PI system.

The same RFC connection can also be used by the PI system to post IDOC acknowledgement messages to the R/3 system once the IDOC has been successfully processed or when errors are encountered by PI.



The PI system registers a Program ID with a web application server gateway to receive RFC calls from the R/3 system. The gateway chosen is typically that of the PI web application server but can also be that of the R/3 system.



Finally a RFC destination is created in the R/3 system. This destination allows the IDOC layer in the R/3 to call the program ID that is registered on the RFC gateway either on the PI system or the R/3 system. The RFC destination in the R/3 system is referenced in the IDOC port configurations.



1.

Defaul t (recommended) option i n sender communication channel.

The default setting is recommended as the configuration is simplified by using a central configuration in the NWA. A single resource adapter is shared between all the sender channels of this option. The details are explained in the following sections. A RFC destination is maintained in the PI system with details of the R/3 system to query the IDOC structure. This connection is created in the section ‘1.a’ below. The destination maintenance step enables the IDOC adapter to create a RFC connection internally for metadata query of the IDOC structure. To support multiple ERP systems the parameter named MultiRepository is used.



The same RFC destination can also be used by the PI system to post IDOC acknowledgement messages to the R/3 system once the IDOC has been successfully processed or when errors are encountered by PI. However if needed a different destination can be maintained. The creation of this destination is outlined in section ‘1.b’.



The registration of the Program ID by the PI system into the RFC gateway is achieved by configuring inboundRA resource adapter in the NWA. This step is outlined in section ‘ 1.c’





The creation of the RFC destination in the R/3 system is described in section ‘ 1.e’

a. Creati ng Default Desti nation in NWA of th e PI System The destination is used by the sender communication channel to retrieve the metadata for the IDoc types that are processed on the communication channel. The destination must point to a SAP web application server (e.g ERP) that contains the IDOC definition. Open NWA (http://:/nwa)

Click on Create button to create a new Destination.

Enter the Destination Name (XI_IDOC_DEFAULT_DESTINATION) and select destination type as RFC.

5


Enter ERP system details below.

Enter the log-on Credentials and click finish.

Once completed, the destination will be added in the available list of destinations. Select this newly added destination and click on Ping Destination button to check if connection is successful. Results will be displayed on top of the page.

6


In case of errors in Ping Destination , check the system and logon details which has been provided while creation of destination. b. Create RFC destin ation in NWA for Backend System (Option al) RFC Destinations can be created with the below name f or metadata read. XI_IDOC_DEFAULT_DESTINATION_. The above destination can also be used for sending acknowledgements but this needs to be explicitly defined in the channel. Separate RFC Destinations need to be created for each R/3 system. Separate RFC destination can also be created for sending acknowledgements in this case naming pattern is not mandatory.

Note: If this is not set the default destination of inboundRA XI_IDOC_DEFAULT_DESTINATION is used for metadata of any idoc messages from the R/3 system. c.

Configuring the resource adapter inboundRA. This configuration is a one-time activity on the PI system. The step is initially executed during the installation process when the CTC template JIDOC is executed. If not configured during the time of installation, it will have to be configured later. Open NWA (http ://< host> :< port>/nwa) resources.



Configuration



Infrastructure



Application

Select Resource Adapters from show drop down list.

7


Filter for inboundRA in the list. The resource of the name inboundRA must already exist if the CTC template is executed during installation.

Then Click Properties tab and enter the details as shown in screenshot below. (If certain property is not shown in the list, it can be added from Add New Property option available). -

Set the value of the Program ID field as XI_IDOC_DEFAULT_ where SID is system ID. Note: This is the same program id which will be used to create RFC destination (TCP/IP) in ERP system as described in step ‘e’. Note : Program ID can be arbitrary but must be unique name for the used gateway

-

Set MaxReaderThreadCount value between 5 – 10 (Default value is 10) Destination Name as XI_IDOC_DEFAULT_DESTINATION Set Local as true. Set BindingKey as PI_AAE_IDOC Save changes. Note : If Local is set to false then default Gateway server and Gateway service of PI system need to be provided while configuring inboundRA.

d. Sender Commun ic ation Channel wi th IDoc_AAE Adapter typ e. Create a communication channel in Integration Directory (In this guide it is IDoc_AAE_Default) as shown below. (Note: The required business systems should be already imported into integration directory from SLD) - Select Adapter Type as IDoc_AAE - Select Default (Recommended) option in RFC Server Parameters. Note: Maintaining Ack Destination is not mandatory. Refer SAP Note 1826256 for further details.

e. Confi guri ng RFC Destination in Sender R/3 syst em. Create RFC Destination of type T in sender R/3 system (In this guide it is P73_AAE) and in technical settings tab select registered server program . Same details need to be provided for Program ID, Gateway Host and Gateway service in RFC Destination which was added earlier while configuration of inboundRA resource adapter in section ‘1.c’ above.

9


Click on connection test to ensure connection is successful with the details specified in RFC Destination.

2. Manual Option in sender communication channel In the manual mode, all the configuration parameters are provided in the channel itself. Sender communication channel with Manual option can be used for test purpose. In case of Manual option we have no control of the gateway. 





The parameters to create a RFC connection to retrieve the IDOC structure are already availabl e in the channel configuration. The same RFC connection can also be used by the PI system to post IDOC acknowledgement messages to the R/3 system once the IDOC has been successfully processed or when errors are encountered by PI. Similarly, the registration of the Program ID by the sender channel into the RFC gateway of the R/3 system is implicitly performed. Here a distinct gateway name cannot be specified in the channel. The creation of the RFC destination in the R/3 system is described in step ‘b’.

a. Sender Commun ic ation channel with IDoc_AAE Adapter type and Manual Option. Create Sender Communication channel (in this guide it is IDoc_AAE_Sender_Manual) in Integration directory 

Select Adapter Type IDoc_AAE and select RFC Server Parameters as Manual. 10




Provide unique Program ID (in our case it is SAP_XI_MANUAL_TEST) as shown in below screen shot. This Program ID will be used later while configuring RFC Destination in sender R/3 system.

System details of R/3 system with valid user id and password need to be provided in channel so that the Program ID is registered in R/3.

b. Confi guri ng RFC Destination in sender R/3 syst em. Create RFC of Type T in sender R/3 system (Tcode sm59) and provide the details as shown below in Technical settings tab. (In this guide it is P73_AAE_MANUAL) 

Program ID name should be the same which has been mentioned in the sender communication channel (IDoc_AAE_Sender_Manual ).



Maintain Gateway host and Gateway service of R/3 system where Program ID has been registered. Save and Click on Connection Test to ensure RFC Destination is working fine without any issues.

11


3. From NWA option in sender communication channel The mode is very similar to the default mode and offers convenience of a central configuration in the NWA. A resource adapter configuration is created manually and is shared between all the sender channels sharing the same resource adapter name. The details are explained in the following sections.

Custom Resource adapter is created as in step ‘a’ below. This adapter can be specified in sender communication channel to receive IDoc from R/3.





RFC destination need to be created in the R/3 system.

a. Create Custom Resource adapter. Create a custom resource adapter in NWA Go to NWA -> Configuration -> Infrastructure -> Application Resources. Click Button Create New Resource -> Select New Resource Adapter –

12


Select Template as ‘com.sap.aii.adapter.idoc.raclonetemplateRAR’ & Enter a name for Application and click Next Enter JNDI Name example ERPCLNT800_RA

Press Next Again -> Enter JNDI Name again and press Tab for save button to activate and Press Save. Now a NWA Resource Adapter is created. Now in the properties tab for newly created resource adapter enter the Program ID(Example : SAP_ERP_NWA) which will be used in RFC Destination in R/3 system, and other details like server,client,logon details etc. Do not change the binding key value which is PI_AAE_IDOC. Create an RFC Destination in R/3 system as done earlier of type ‚‘T‘ and enter the Program ID(SAP_ERP_NWA) which has been mentioned in properties on Resource Adapter ERPCLNT800_RA Create a communication channel (In this guide it is IDoc_AAE_NWA) in Integration Directory as per below screen shot. - Select Adapter type IDoc_AAE. - Select RFC Server Parameters as From NWA and provide the Resource Adapter Name as ERPCLNT800_RA.

If required separate Java IDoc communication channels can be created for each customer interface scenario which is using one central NWA configuration .

13


b. RFC destin ation in Sender ERP system.

Create RFC destination in Sender R/3 system as done in section 1.e for Default Mode in Sender IDoc Adapter. Enter the Program ID(SAP_ERP_NWA) which has been mentioned in properties of Resource Adapter ERPCLNT800_RA

CONFIGURATION REQUIRED FOR RECEIVER CHANNEL WITH IDOC_AAE ADAPTER TYPE The objective of the receiver channel configuration is to establish a technical connection from the PI system to the R/3 system for sending the IDOCs from the former into the latter. The connectivity is established using RFC technology. Single RFC connection needs to be created on PI system. The following options are available. The PI system can be configured with a RFC destination to specify the content of the RFC connection parameters. The PI channel can refer to the RFC destination in the NWA.



The RFC connection parameters can be directly maintained in the PI channel.



A new java connection factory is created and the required parameters of the RFC destination are maintained in the connection factory. The connection factory is then referenced in the PI channel.



Note: The Java IDOC Receiver Adapter is a bit more strict when checking the syntax of the IDOC XML. For “BEGIN” and “SEGMENT” fields of the IDOC XML and the adapter expects the constant value “1” .

SAPJRA application instance allows idoc adapter to receive iDoc messages (sender adapter).The number of Reader threads or parallel server connections registered to the gateway can be configured in the Resource adapter.The property is called MaxReaderThreadCount. Set MaxReaderThreadCount value between 5 – 10, Default value is 10 and is the highest which is recommended to this property. Local : To improve performance and tie the Lifecycle of gateway with that of Adapter engine it is possible to use local gateway. There is local gateway available with Adapter engine installation.For this you need to set the 'Local' property to true. However if you do this at SAP Backend side too the same gateway needs to be chosen. In SM59 transaction you have to enter local gateway details manually. If 'Local' property is chosen, the GatewayServer and GatewayService configured in inboundRA has no significance.Also please remember to set Local property to false if you don't wish to use Local gateway. multiRepository : The miltiRepository property should not be changed manually as it is populated by the IDoc_AAE adapter. It specifies a list of RFC destinations from the PI system to several SAP systems that are used to query for IDoc metadata when parsing the received IDoc documents or IDoc document lists to valid IDoc-XML. The property value consists of pairs =XI_IDOC_DEFAULT_DESTINATION_ separated by “;” where is the SID name of the sender system of a started sender channel.

Binding Key : It is binding key used to activate IDoc message listener and constant value ‘PI_AAE_IDOC’ has to be maintained for this property.

CHOOSING RFC SERVER PARAMETER OPTION IN IDOC_AAE ADAPTER

Default (Recommended): Default mode in sender communication channel can be used to receive IDoc from multiple senders.



Channel configuration is simple compared to manual mode as no authentication parameters are maintained in the channel.



No requirement of the PI Integration Developer Role for administrati on of the connection details. And therefore ideal configuration for long term operational maintenance of the IDOC connection.



Basis administrator role is required for maintenance of the connection parameters. The PI integration developer testing phase requires pre configuration activities by BASIS Administrator. Uses logical destination which allow reuse of connection data. Connection can be shared between multiple R/3 systems . However it may not give good isolation as we have multiple R/3 systems are reusing same set of inbound connections. Ideally to be used with PI Gateway (in InboundRA resource adapter), this reduces the chances of Gateway related issues and reduces the channel start and stop time. Could lead to monitoring issues as the request processing is not tied to channel lifecycle (server connection may be started even when channel is stopped).

Manual: 



Quick and easy configuration by the integration developer is enabled. No NWA Administration role is required for configuration and is ideal during adhoc development time testing. Manual option can be used for test purpose.

Operational maintenance of the connection settings on a long term operational lifecycle of the integration scenarios requires the PI developer role.





Cannot add trace level or log level since the server connections are per ABAB Backend system.

NWA: 

NWA Option can be used if there are numerous senders/receiv ers to be configured



Simple Configuration. No maintenance of authentication parameters in the channel.



Flexible, can be used for error tracking as separate RAs can be created per incoming servers (trace level and server connections can be increased).

NWA option can be used for communication with Non-SAP systems using Java IDoc_AAE adapter type.
