Strategic Sourcing with RFx 
You can use this business scenario to source goods using RFx (request for information, request for proposal, and/or request for quotation). You can use this business scenario with or without integration of the sourcing application. The sourcing application helps you, as a professional purchaser, to process your requirements and to determine the best source of supply. You can also integrate document storage functionality – maintained in cFolders – in the RFx. After you have received bids from suppliers, you can create a purchase order or contract (local or global outline agreement) directly from the sourcing application or in SAP Bidding Engine as a result of the RFx.
You can implement this business scenario with different releases of the relevant application components. However, only certain combinations are valid.
