Purchase Order Processing 
This function enables you to map the entire procurement process in supplier self-services (SUS) using sales orders (SUS purchase orders).
Integration
The system automatically creates a purchase order in supplier self-services when a purchaser enters the purchase order in the procurement system and sends it to SUS.
Note
The procurement system can be either SAP Supplier Relationship Management (SAP SRM), Materials Management (MM), or a non-SAP procurement system, depending on which business scenario you have implemented.
Features
You can display and edit purchase orders including purchase orders with a service item with hierarchical structure, and send purchase order responses to the purchaser. In a purchase order response, you can confirm or reject each individual item or all items in the purchase order. You can also create or edit schedule lines.
You can create follow-on documents, such as advanced shipping notifications (ASN), confirmations (service entry sheet), and invoices, on the basis of a purchase order. The follow-on documents that can be created depend on the procurement system used, and on the document control settings the purchaser has made in the purchase order.
Note
In the Service Procurement business scenario, you use confirmations. In the Plan-Driven Procurement with Supplier Integration business scenario, you use ASNs.
