Has anyone performed and successful customised ATP checks. If so how did they go about it - user exits?
The current ECC 6.0 (unlike APO) has no multi level facility and we have a requirement for multi level ATP. In addition to this we also want to run ATP on a first in first out principle in terms of reservations of stock and again this is not somethings SAP ECC 6.0 provides.
I wondered how others have tackled this problem? One day SAP may extend functionality on ECC 6.0 !!!
