Business Process: After a PO is sent to the vendor, the vendor reply with confirmation dates and quantities, often times this is different from what our delivery date on the PO requested (thus we can't use the order ackowledgement text field), we also need this delivery date and quantity be reflected in MRP/MD04
Right now following SAP standard, if we enter confirmation key 0001 and AB, the line in MRP changes to a shpgNt and if the situation is a pull in, MRP will no longer try to pull in this shpgNT and instead try to pull the next available unconfirmed PO line. the same behavior if we enter "LA"
If all the POs are confirmed (MD04 only contain shpgNTs), then MRP actually create a new preq instead of trying to pull in any of the shpgnts
The business want a behavior where the MRP would still put the pull-in message on the shpgnt (or whatever mrp element it end up being)
using all standard configuration
any ideas? thanks in advance
