You can only route an RFC if you provide a valid SBCHEADER with your function call. To route RFCs through the routing listener, you must include a header table that contains information that the routing listener uses to route the RFC.
Note:
Before the routing listener can receive an RFC, you must define an RFC listener for the RFC destination defined at the calling SAP system. For instructions, refer to
Listeners.
To send an RFC to the routing listener, you must configure the SAP system to register the RFC listener as an RFC destination. For instructions on how to create an RFC Destination, refer to
Creating an RFC Destination on an SAP
System.
