There are three custom fields which are added in SRM SC and PO at item level. My requirement is to map these three custom fields to three standard fields in ECC PO. Can any one please explain me, how the replication of SRM PO to ECC PO happens? I could find a function module "B470_PO_CREATE". Can any one tell me through which transaction or program this FM will be triggered.
Any useful answer will be rewarded
