we have SAP and SIEBEL system, and crate/update customer info(or say account) at SIEBEL first, then send account info to SAP via IDOC, message type is DEBMAS06.
Now there is a bug. create/update contact info at siebel, it always create new contact at SAP when inbound to SAP system.
Is there anyone can give me any advice about how to fix this bug?
Thanks & best regards.
