We have a problem with our Ack (ALEAUD).
Our scenario is SAP --> XI --> FILE
Everything seems to be configured correctly and we receive the Ack's back into the Sending SAP system. However the Status of the original IDoc is not updated.
After further digging I have noticed that the field DOCNUM from the E1STATE segment is missing.
I have seen many threads relating to the same error but none seem to solve it...
Could anyone provide some insight into this matter?
