There is a service agreement.Billing document is generated for that service agreement.The issue is that the billing document is having one PO number. Then the billing document is converted into an IDOC, and sent to the customer.
the IDOC that gets generated for Billing document is having a different PO number.
Can you please tell me why and how it gets changed.
How can I find from where the data in IDOC is filled and how can we find the function module relating to that IDOC.
Thanks in advance
