I started reading about SAP Bidding Engine on help.sap.com and got confused with the very first lines.
Purchasers can use SAP Bidding Engine to create and process bid invitations and live auctions for products and services. Bidders can use SAP Bidding Engine to submit bids in response to these bid invitations and auctions.
In general a Purchaser is some one who wants to purchase goods/services and similarly a bidder is also some one who BIDS for goods/services and buy them.
So what is the difference here between purchaser and bidder?
Please explain the difference from SRM perspective..
Sorry if it sounds as very basic question ..
