We have a problem processing an inbound invoice IDoc when all items have a header discount (e.g. 10%). The IDoc (from an EDI-System) contains the total sum (as a sum of all item prices) and the total discounted sum.
The SAP application doesn't process this IDoc by saying: "Can't process, there is a difference between of x EUR between debit sum and credit sum".
This is the difference between the sum of all items and the discounted sum. What do I have to do, to get this thing into the system? Do I need programming in ABAP or can it be done by using the right qualifier combination in E1EDS01?
Help please...
