Integration of Sources of Supply
The integration of sources of supply is controlled by source of supply determination in an integrated system landscape.
An active integration model is available for purchase orders and purchase order requisitions.
A transportation lane is modeled between locations in SAP APO. Product-specific transportation lanes are assigned for the products to the transportation lane. The procurement form is defined within the product-specific transportation lane. An external procurement relationship can also be assigned from the ERP system.
If a contract exists in SAP APO, the ERP system does not perform source of supply determination when transferring purchase requisitions from SAP APO.
Here, the following cases exist:
· The external procurement relationships from the ERP system were transferred to SAP APO. An external procurement relationship was assigned to the purchase requisition as a source of supply in SAP APO. This source of supply is transferred to the ERP system.
· A transportation lane was created (manually) in SAP APO. The source location can be a vendor location or a plant location.
¡ Vendor location
SAP APO transfers the vendor to the ERP system. If a source list requirement exists, the ERP system uses the source list in the ERP system to determine a source of supply. If no source list requirement exists, the ERP system searches for an info record for the vendor specified in accordance with the procurement form defined in SAP APO (standard, consignment, or subcontracting).
¡ Plant location
Here the ERP system also takes into account the source list if a source list requirement exists. If no source list requirement exists, the ERP system generates a stock transport requisition for the supplying plant from SAP APO.
If SAP APO has not transferred a source of supply, in other words, if SAP APO creates an anonymous purchase requisition without a source location, the ERP system automatically performs source of supply determination. You can deactivate the automatic source of supply determination in the IMG for CIF under Application-Specific Settings and Enhancements → Settings and Enhancements for External Procurement → Inbound Processing of Purchasing Data → Activate/Deactivate Source of Supply Determination/Source List Integration.
In the case of the automatic source of supply determination, the ERP system first interprets the special procurement key in the material master record, and creates, as required, a stock transport requisition, consignment requisition, or standard purchase requisition using source of supply determination. Subcontracting is not possible here. For this, it must also be possible to determine a purchasing organization, and a purchasing info record must be present in the ERP system. For more information, see SAP note 395410.
The ERP system can create purchase orders from SAP APO in two ways:
· In SNP, purchase orders can be created in deployment and in the TLB. For more information, see Deployment and Transport Load Building.
