We have a requirement to synchronise the vendor master changes from SAP S4 HANA system to ECC for a specific vendor account group ( Employee Vendor). If we made any changes to the vendor master in S4 system then it should trigger the same change in ECC system also.
I have searched several topics and found it can be done through Idoc ("Cremas"), But don't found a proper document.
If anyone has already worked on this, Please share a document/link here or suggest how to proceed.
You can implement BADI to catch event BEFORE UPDATE and call IDOC to update vendor in ECC system. So, I have already done a quick check S4 Hana system and there may be 2 solutions:
1. Implement BADi BUPA_GENERAL_UPDATE
2. Add new function on event DSAVC - Complete Data for Saving, tcode BUS7
Hope help you,
