IDOC parser and domain

The IDOC domain processes messages that are sent to the broker by SAP R3 clients across the MQSeries® link for R3.

A typical IDoc message structure that has been sent from SAP to the MQSeries link for R3 is represented in WebSphere Message Broker as the root element followed by:

You can create message models to represent SAP IDocs using the IDOC domain; see The IDOC domain. Messages in this domain are processed by the IDOC parser.

WebSphere Message Broker uses the IDOC parser to read and write messages that belong to the IDOC domain. When reading a message, the IDOC parser constructs a message tree from a bit stream. When writing a message, the IDOC parser creates a bit stream from a message tree. The IDOC parser calls the MRM parser to parse and write the user-defined segments of an IDoc.

For more information about how to create the message model for an IDoc, see Building the message model for the IDOC parser.
