In this section, you can read about how data for purchase orders and purchase requisitions is exchanged between SAP Advanced Planning and Optimization (SAP APO) and the ERP system through Core Interface (CIF).
You have created an active integration model for purchase orders and purchase requisitions.
You have the following options for external procurement in SAP APO:
Standard purchase order/purchase requisition
Subcontracting purchase order/purchase requisition
Stock transport order/stock transport requisition
Consignment order/requisition
Purchase order/purchase requisition for make-to-order production and engineer-to-order production
Only these types of purchase orders and purchase requisitions are integrated through CIF.
You can differentiate between two cases of integration:
The purchase order or purchase requisition is generated in SAP ERP and is transferred to SAP APO. The target system performs rescheduling.
The purchase order or purchase requisition is generated in SAP APO and is transferred to SAP ERP. The target system performs rescheduling. For more information, see Creation of Purchase Orders and Purchase Requisitions from SAP APO.
For more information about enhancements to the interface, see Customizing in the relevant system:
