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 is part of the advanced adapter engine and is a java implementation which does not use ABAP services. The configuration for IDoc_AAE 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) 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: 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. 3 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. There are different RFC connections that are maintained on PI and 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.g ERP) that contains the IDOC definition. This connection is created in the section ‘1. However if needed a different destination can be maintained. Finally a RFC destination is created in the R/3 system. A RFC destination is maintained in the PI system with details of the R/3 system to query the IDOC structure. The destination maintenance step enables the IDOC adapter to create a RFC connection internally for metadata query of the IDOC structure. This step is outlined in section ‘1. The connectivity is established using RFC technology. The RFC destination in the R/3 system is referenced in the IDOC port configurations.Configuring Java IDoc Adapter (IDoc_AAE) in Process Integration 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. To support multiple ERP systems the parameter named MultiRepository is used. A single resource adapter is shared between all the sender channels of this option. 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. The creation of this destination is outlined in section ‘1.b’. The PI system receiving the IDOC needs to query the sending R/3 system to understand the structure of the received IDOC.a’ below. The registration of the Program ID by the PI system into the RFC gateway is achieved by configuring inboundRA resource adapter in the NWA.c’ The creation of the RFC destination in the R/3 system is described in section ‘1. Creating Default Destination in NWA of the 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. Default (recommended) option in sender communication channel. 1. Open NWA (http://<host>:<port>/nwa) Configuration Infrastructure Destination.e’ a. 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. An RFC connection is created for this purpose on the PI system. The details are explained in the following sections. The default setting is recommended as the configuration is simplified by using a central configuration in the NWA. 4 . The destination must point to a SAP web application server (e. Configuring Java IDoc Adapter (IDoc_AAE) in Process Integration Click on Create button to create a new Destination. Enter the Destination Name (XI_IDOC_DEFAULT_DESTINATION) and select destination type as RFC. 5 . the destination will be added in the available list of destinations. Enter the log-on Credentials and click finish. 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. Once completed.Configuring Java IDoc Adapter (IDoc_AAE) in Process Integration Enter ERP system details below. 6 . c. The step is initially executed during the installation process when the CTC template JIDOC is executed. 7 . This configuration is a one-time activity on the PI system. Separate RFC Destinations need to be created for each R/3 system. 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. b. If not configured during the time of installation. Create RFC destination in NWA for Backend System (Optional) RFC Destinations can be created with the below name for metadata read. The above destination can also be used for sending acknowledgements but this needs to be explicitly defined in the channel.Configuring Java IDoc Adapter (IDoc_AAE) in Process Integration In case of errors in Ping Destination. check the system and logon details which has been provided while creation of destination.

Manual Option in sender communication channel In the manual mode. Sender communication channel with Manual option can be used for test purpose. In case of Manual option we have no control of the gateway. Here a distinct gateway name cannot be specified in the channel. 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. The parameters to create a RFC connection to retrieve the IDOC structure are already available 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. The creation of the RFC destination in the R/3 system is described in step ‘b’. all the configuration parameters are provided in the channel itself.Configuring Java IDoc Adapter (IDoc_AAE) in Process Integration Click on connection test to ensure connection is successful with the details specified in RFC Destination. 2. 10 . Similarly. the registration of the Program ID by the sender channel into the RFC gateway of the R/3 system is implicitly performed.

Local : To improve performance and tie the Lifecycle of gateway with that of Adapter engine it is possible to use local gateway.The number of Reader threads or parallel server connections registered to the gateway can be configured in the Resource adapter.Configuring Java IDoc Adapter (IDoc_AAE) in Process Integration Properties of InboundRA resource Adapter MaxReaderThreadCount : IDoc works on the SAPJRA and JCo 3 model. If 'Local' property is chosen.The property is called MaxReaderThreadCount. 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. 27 .” where <SID> is the SID name of the sender system of a started sender channel. However if you do this at SAP Backend side too the same gateway needs to be chosen. 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. Default value is 10 and is the highest which is recommended to this property. Set MaxReaderThreadCount value between 5 – 10. the GatewayServer and GatewayService configured in inboundRA has no significance. In SM59 transaction you have to enter local gateway details manually. The property value consists of pairs <SID>=XI_IDOC_DEFAULT_DESTINATION_<SID> separated by “. SAPJRA application instance allows idoc adapter to receive iDoc messages (sender adapter).Also please remember to set Local property to false if you don't wish to use Local gateway. There is local gateway available with Adapter engine installation.For this you need to set the 'Local' property to true. can be used for error tracking as separate RAs can be created per incoming servers (trace level and server connections can be increased). Manual: Quick and easy configuration by the integration developer is enabled. Manual option can be used for test purpose. Connection can be shared between multiple R/3 systems . Operational maintenance of the connection settings on a long term operational lifecycle of the integration scenarios requires the PI developer role. However it may not give good isolation as we have multiple R/3 systems are reusing same set of inbound connections. Flexible. 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). Cannot add trace level or log level since the server connections are per ABAB Backend system. The PI integration developer testing phase requires pre configuration activities by BASIS Administrator. Basis administrator role is required for maintenance of the connection parameters. And therefore ideal configuration for long term operational maintenance of the IDOC connection.Configuring Java IDoc Adapter (IDoc_AAE) in Process Integration 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. No NWA Administration role is required for configuration and is ideal during adhoc development time testing. Uses logical destination which allow reuse of connection data. Channel configuration is simple compared to manual mode as no authentication parameters are maintained in the channel. Ideally to be used with PI Gateway (in InboundRA resource adapter). NWA: NWA Option can be used if there are numerous senders/receivers to be configured Simple Configuration. this reduces the chances of Gateway related issues and reduces the channel start and stop time. No requirement of the PI Integration Developer Role for administration of the connection details. 28 . No maintenance of authentication parameters in the channel.
