Process documentationExternal Sourcing for Purchase Requisitions Locate this document in the navigation structure

 

In order to generate follow-on documents for purchase requisitions created in the SAP ERP system, you must assign a valid source of supply. If there are no valid sources of supply in SAP ERP, the purchaser can carry out external sourcing using the SAP SRM system.

There are two processing modes available for transferring purchase requisitions to the SAP SRM system:

  • Background mode

    Purchase requisitions are transferred to SAP SRM automatically, and are created as external requirement documents in the SAP SRM system. Subsequently, the purchaser can process and convert the external requirement document into a follow-on document (for example, a purchase order, contract, RFx or auction) directly in the SAP SRM sourcing application.

  • Online mode

    Purchasers transfer purchase requisitions manually using the Collaborative Processing of Purchase Requisition (CPPR) application. In online mode, purchasers can choose to either transfer purchase requisitions to SAP SRM by creating an external requirement document in SAP SRM, as in background mode, or create an RFx for the purchase requisition directly in SAP SRM. If the purchaser chooses to create an RFx directly in SAP SRM, no external requirement is generated for the purchase requisition.

Note Note

Before you configure this process, you must first configure the basic settings for the Plan-Driven Procurement with Plant Maintenance business scenario. You do this in SAP Solution Manager under   <project name>   SAP SRM <release>   Basic Settings for Plan-Driven Procurement   Basic Settings for Plan-Driven Procurement with Plant Maintenance  .

End of the note.
