There is a statement in SAP help portal that said:
The vendor may be required to comply with the technical delivery terms and the quality assurance agreements when a quotation is made from us to the vendor. If one of the required documents is not available or not released when a purchase order is opened, the function is blocked.
I have one questions on this statement.
1 - How do I configure in the system to tell R/3 that if I do not receive those two documents, system should prohibit me from creating a purchasing order.
