Idoc with error message when coming from middleware but not in we19
I am facing a very strange issue !
I have a Z - Idoc type and corresponding inbound function module for creating schedule lines i.e. doing something what me38 does.
When my middleware i.e. Mercator Websphere is sending the idocs, they fail with the error message in the status record as
Field EKET-MENGE (19) does not exist in the screen SAPMM06E 1117.
But when I try processing the same idoc using we19, the scheduling lines are created and the schedule agreement is changed.
Is there any difference between we19 and when idocs come from the middleware ?
Points would be rewareded if useful answers received.
