Requirement is to change PO level Vendor address in runtime during PO Create/Change since one vendor can have multiple addresses.
Address id is generated separately in Z tables for multiple address.
Please let me know place to change ABAP code in order to update selected Vendor address. I tried user exits "EXIT_SAPMM06E_013"
also BADI = "ME_PROCESS_PO_CUST" but not able to update.
