I want to use the Create Agreements function in the Buyer Work Center in Purchasing module. I noticed that I can create the agreement line using three different methods such Catalog, Favorites and Upload. However, I need to use iProcurement responsibility in order to define those methods to be available. Do I need to purchase a separate product license for this? We don't have any plan to implement the iProcurement for the individual users in our procurement process. I need the iProcurement in order to make the Buyer Work Center to work only.
