Sending IDocs with ALE from an SAP System to Adapter for SAP
The routing listener receives IDocs from an SAP system if the function module (INBOUND_IDOC_PROCESS or IDOC_INBOUND_ASYNCHRONOUS) has no RFC adapter service associated with it. When the routing listener receives the IDoc, the sender, receiver and message type are extracted from the IDoc itself. The routing listener uses this information when determining where to route the IDoc.
Important:
Before
Adapter for SAP can receive the IDoc, you must define an RFC listener for the corresponding RFC destination defined at the calling SAP system. For instructions, refer to
Listeners.
Note:
For information about how to map the IDoc information into another format for use by another application, refer to
Mapping IDocs to Other Formats.
