I have set up plan-driven procurement in the extended classic scenario in SRM 5.0 with an ECC 5.0 back-end. When I assign a vendor to a shopping cart in the sourcing cockpit for an external requirement, it disappears from the worklist. As soon as I have run program BBP_GET_STATUS_2 and I run transaction BBPSOCO01 again, the SC will appear in the worklist again although a PO has been created in both SRM as in the Back-end system. The status of the SC is ordered, the Purchase Requisition is not send again to SRM and I have implemented all relevant notes for program BBP_GET_STATUS_2. How can I prevent that shopping carts are being ordered multiple times? The problem is similar to the problem from KA posted on 9 July 2007, only this is not yet solved.
