Purchase Requisition (B):A purchase requisition is an internal request for goods or services. From this document, an RFQ can be generated to solicit bids from suppliers.

Scheduling Agreement (A):A scheduling agreement is a long-term procurement agreement with predefined delivery schedules and cannot be used to create an RFQ.

Purchase Contract (C):A purchase contract is a formal agreement with a supplier and is not used to generate RFQs.

Purchase Order (D):A purchase order is a legally binding document issued to a supplier after the RFQ process, so it cannot be used to create an RFQ.
