my need is very simple, when i save my purchase requisition i need to access in modification to items (standard fields) of my document.
I'm looking for a few days on SDN or Google but without success, the question has often been discussed but the answers are not accurate or some people say "try this or this" but it doesn't work.
There was an answer to use the Badi ME_PROCESS_REQ_CUST, but all these methods do not suit me. Some people proposes to use the method PROCESS_ITEM or POST. For the first i need to work with global items not line by line and in the method POST i do not have access to lines.
So can you help me ?
