Procurement of External
Requirements 
Use
As the central procurement system, SAP Enterprise Buyer can work together with various SAP and non-SAP systems (planning systems as well as executing systems) and can procure indirect and direct requirements that have been created in systems outside of Enterprise Buyer (external systems).
Integration
Enterprise Buyer and SAP Components for Procurement of Direct Materials
· Advanced Planner and Optimizer (SAP APO)
· Material Requirements Planning (SAP PP-MRP)
Enterprise Buyer and SAP Components for Procurement of Other External Requirements
· Plant Maintenance (SAP PM)
· Project System (SAP PS)
From an R/3 System, Enterprise Buyer takes requirements in the form of a purchase requisition. From R/3 Release 4.0, you can also take requirements from R/3 that contain services.
Enterprise Buyer and Non-SAP Components
Integration of non-R/3 Systems is possible via the open XML interface. The XML inbound interface can process direct and indirect external requirements and generate local purchase orders from them.
Sourcing
Sourcing is carried out automatically for the external requirements. Depending on the Customizing settings, Enterprise Buyer then either generates purchase orders immediately or transfers the items to the purchaser’s sourcing application. See Sourcing of Requirements.
For more information, see the Supplier Relationship Management Implementation Guide (IMG): SRM Server ® Sourcing ® Define Interactive Sourcing for Product Categories.
Third-Party Order Processing
The interface supports the special procurement form third-party order processing.
Service Grouping
In the Sourcing application the system displays groupings (not a multiple-level hierarchy) that have been transferred from external systems.
· Service items appear grouped by service package
· Enterprise Buyer transfers material items in the Standard without grouping You can achieve this grouping using a Business Add-In.
See the path in the Plug-In IMG: Integration with Other mySAP.com Components ® Supplier Relationship Management ® Business Add-Ins für SRM (BAdIs) ® Process Outgoing Requirements
