Assignment of Existing Sources of
Supply 
Use
SAP Enterprise Buyer automatically determines existing sources of supply for requirements. As the strategic purchaser or employee responsible for sourcing, you can have the system propose sources of supply and assign them to an item.
The system provides the following starting points for the sourcing proposal:
· The item overview of the purchase order (only in change mode)
For more information, see Purchase Order Processing.
· The purchaser’s Sourcing application
For more information, see Sourcing of Requirements.
· The vendor list
For more information, see Vendor List.
Prerequisites
You have entered contract items for the selected product in Enterprise Buyer or product linkages with vendor-dependent prices in the CRM system via the SAP menu path: Master Data ® Product ® Maintain Products.
Features
Display sources of supply
For the selected items, the overview of the sources of supply found displays general data and key figures on the vendors, such as
· Current purchase order value
The total value of all selected contract items for this vendor (or vendor-dependent prices).
· Best purchase order value
At a glance, you can identify the total of the cheapest items for suggested vendors. This is particularly helpful if several vendors have the same coverage (for example, 100 %). It helps you see immediately which vendor offers the best price.
· The percentage share of the sourcing items that the vendor can supply.
Detail Display in Multiple Views
Enterprise Buyer displays details on possible vendors in an overview tree that the purchaser can sort in the following ways using tabs:
· According to purchase order items for each of the vendors found
· According to contract items for each of the vendors found
· According to requirement items
If you call up the source of supply proposal from the purchase order, this view is not available.
For a selected vendor, you see the following sources of supply if they exist:
· Contract items
· Vendor-specific prices (product linkages)
· Entries in the vendor list
Assigning sources of supply
In the overview tree, you can transfer sources of supply using checkboxes. You can:
· Manually select one or more sources of supply from one vendor for each requirement
This also applies to items whose price equals 0.
· Have the system automatically determine and select for each vendor the cheapest contract item or product linkage for an item (see Comparing Prices below)
Displaying Vendor Evaluation
The purchaser/sourcer can run a SAP Business Information Warehouse (SAP BW) evaluation for the selected vendor. This displays key figures on reliability regarding quantities, delivery performance and price. Using average values concerning purchase order value and the number of purchase order items, the user can better assess the quality of the vendor. For more information on vendor assessment, see the documentation on SAP BW.
Depending on the application that sourcing calls up, you can use your own BW evaluations with other key figures in addition to the standard evaluations.
For more information, see the Supplier Relationship Management IMG: SRM Server ® Cross-Application Basic Settings ® Define Logical Systems and Template Names for BW Reports
Comparing Prices
Enterprise Buyer automatically determines for a vendor and required item, the cheapest contract item or product linkage and highlights it in color. The purchaser can thus easily identify and select the best conditions.
Updating the Purchase Order Value
After selecting suggested sources of supply, you can have the system recalculate the total of all currently assigned items at the touch of a button.

The system transfers the selected source of supply into the calling application. If you have called up the source of supply proposal from:
The purchase order, then Enterprise Buyer puts the selected item with the assigned source of supply into the purchase order.
Sourcing, then Enterprise Buyer puts the items into the Sourcing work area so that you can carry out further sourcing activities (for example, Create Bid Invitation).
The vendor list, then there is no data transfer. The source of supply proposal simply provides information and there is no compulsion to use the sources proposed.
