Converting requisitions into PO's
Our users create shopping carts in SRM. Once approved, they become a purchase requisition in SAP. If the items were to a fixed vendor, a PO is automatically created. However, for those times that a preferred vendor was used, the requisition is manually turned into a PO. Is there a way to prevent multiple requisitions on the same PO even though the steps are done by human intervention? Each requisition is unique and should not be combined on one PO.
