Transfer a PReq to an External Procurement System (SAP Library

Transfer a PReq to an External Procurement System

Use

Using this function you can transfer purchase requisitions to an external procurement system from maintenance orders, service orders, and network, for example SAP Enterprise Buyer (EBP). For more information about the SAP Enterprise Buyer, see the SAP Library under Bid Invitation and Quotation with the Enterprise Buyer.

Prerequisites

You installed the SAP R/3 Plug-in for the EBP.

You require this plug-in even if you do not use the EBP, but rather a different external procurement system.

You determined in which system (external procurement system or SAP R/3) purchase order handling for a purchase requisition should take place. You do this by defining a combination of purchasing group and material group referring to another system by using a profile. Use the transaction SM30 in the Views V_T160EX and V_T160PR. Or you can determine a purchasing profile by using your own logic in the Customer Exit BBPK0001.

The system creates a purchase requisition (PReq).

Features

Communication between SAP R/3 and the external system occurs via a qRFC (queued Remote Function Call).

Activities

The system carries out the following activities automatically:

The system decides whether purchase order handling should be carried out in the SAP R/3 system or in a different external system based on the settings in Customizing.

If handling should occur in an external system, the system transfers the purchase requisition to the external system and sets a flag in the SAP R/3 System that prevents a purchase order from being created.

The rest of the purchase order handling (sourcing and creating a purchase order) occurs in the external system.

After the invoice is created the external system decides whether the goods receipt and invoice receipt should be posted to the external system or again to the SAP R/3 System. Once handling occurs, a message from the external system updates the status of the purchase requisition in SAP R/3. Otherwise the purchase order is transferred back to the SAP R/3 System and handled there.

Creating and deleting commitments occurs in both scenarios in SAP R/3.

If you change the purchase requisition in SAP R/3, the system transfers the entire document with its changes to the external procurement system.
