 Procurement Using an External Procurement System


Using this function you can order materials or services in an external procurement system from maintenance orders, service orders, and networks, for example SAP Enterprise Buyer (EBP).


You can transfer material components or services for which you want to create a purchase requisition(PReq) from an external catalog using the open catalog interface (OCI) (see Catalog Interface (OCI- Open Catalog Interface) ).


  • 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.

  • In the Customizing of the Plug-In system, under Start of the navigation path Supplier Relationship Management Next navigation step Planning-Controlled Procurement, End of the navigation path you determined in which system (external procurement system or SAP system) purchase order handling for a purchase requisition should take place.

    You can also use the Customer Exit BBPK0001 and thus determine your own logic in the purchasing profile.
