File-sap-file using bpm
My scenario is source file sends data to sap(zrfc) which adds 5 fields to the source structure and sends it to target. the source and target structure except the 5 fields from sap is added to the target structure. this scenario is using bpm. And the ZRFC id created using tables tab.so I want to know how many message types, message interfaces and how the mapping goes about. and how to design in integration process in integration repositiory.
thanks & regards,
