The Relevant RFQ Module provides the ability to generate and send requests for quotation to vendors for inventory and non-inventory items, as well as for services and estimates. PO requisitions and estimates provide the ability to create new RFQs, or to add items to existing RFQs. The system automatically generates a list of potential vendors, based on PO history. "Prospective" vendors can be added to the list (vendors who are not in the standard Vendor Master file). When bids are received from the vendors, the prices and special charges are entered and the winning vendors are selected. The RFQs can then be converted to new or existing purchase orders. If a prospective vendor is selected, the system automatically creates the required Vendor Master records for that vendor when the PO is created.
