Has anyone come across a way to deal with this scenario in SAP? MRP will give a purchase order an exception 20 only if the entire PO quantity is in excess. In many cases we only need a partial quantity of the material and the rest could be cancelled. We don't have a way to identify those purchase orders where we could reduce the PO quantity to avoid excess inventory. Has anyone been able to find a way to identify these purchase orders available for quantity reduction?
