Dear Gordon,
Thank you for your answer.
It has been helpul.
I do not if there is a link , bt I check some Idoc ( ORDER and ORDCHG) and have remark that some ORDER have been created with wrong master data and without out E1EDP20 segment ( quantity)
for exemple :
the vendor in the control rec does not match with the Schedule agrement and the article ..
Do you have any idea ?
thank you and best regards
