ALE pass-through IDoc business object structure
During ALE processing, the adapter exchanges business objects with the SAP application.
The message tree contains a BLOB field that represents the IDoc. The BLOB field is modelled as a HexBinary type in the XSD file. The message tree contains the stream data (the BLOB field), which is the entire data of the IDoc. The transaction ID, iDoc type, and queue name fields contain information about that data and how it has been transferred.
The transaction ID (SAPTransactionID) is used to ensure once-only delivery of business objects, and the queue name (qRFCQueueName) specifies the name of the queue on the SAP server to which the IDocs should be delivered. If you are not using transaction IDs or queues, these properties are blank.
To parse the IDoc control record, select Parse the IDoc Control Record when you run the Adapter Connection wizard.
