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. It also allows data of another format supported by the broker (for example, JMS) to be mapped to an IDoc stream.

The class name of the parser that is needed is defined in the Format field in the MQMD header of the input message. The parser creates the message tree from an input message in a specified format. This format must be followed when a message tree is built in a WebSphere Message Broker message flow.

For a SAP IDoc message the name of the high level element (the last child of the root element) must be IDOC to match the message domain supported by the parser.

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:
