User exit for blocking vendors for POs but not for RFQs
We want some vendors to be blocked from creating a PO but not with RFQ. We have used MK05 because there is an option there that the vendor can be blocked in Purchasing Organization and to a specific point that a PO will be the only blocked transaction but it is not working properly. It laso blocks the RFQ creation. Is there an available user exit for this?
Check with your abaper if the BADi - ME_PROCESS_PO_CUST with method PROCESS_HEADER can be used to make your custom check & prevent saving of PO. But for this you will have to maintain some criteria, maybe some Z table which contains all Vendors for which PO should not be created, so this BADi can refer to this Z table.
Hope the above helps.
