The ALE IDoc messages that are sent to, and received from, SAP applications using the WebSphere® MQ Link for R3, can be processed by the IDOC parser, which requires a message model to interpret the data correctly. This topic describes how to build the message model.
Before you start:
Obtain SupportPac™ IA0F, which contains detailed instructions to help with the creation of message sets for the IDOC parser.
Create your message model.
Add the message set to a broker archive (BAR) file and deploy the BAR file to a broker execution group. The IDOC parser uses the MRM parser to parse the IDoc segments that you have defined.
The Message Domain property, the message set name, and the Custom Wire Format name, are used when you create a message flow to process an IDoc. These names appear as the values of the Message Domain, Message Set, and Message Format properties of an MQInput node. Do not supply a Message Type property on the MQInput node because the IDOC parser uses the contents of the SAP-defined IDoc DD field segnam to provide the name of the message.
