we have a SRM-system with a R/3 backend and added some customer fields to the accounting or purchase orders. The question now is how to transfer the cuf-data from SRM to R/3.
There are the function-modules like B470_PO_CREATE of package BBP_BD which are dealing with the data and include the cuf-data. For my understanding i should write my own driver by copying such a function-module and call the remote BAPI (also a copy of the SAP-functionmodule BAPI_PO_CREATE) that has the cuf-data as import (original SAP doesnt have that) and save them according to that.
The question now is how can i make SRM using the new functionmodule and what is the best practice for that problem.
thanks for your help.
