This section gives an overview of the business data flow between SAP Supply Network Collaboration (SAP SNC) and the backend systems at the customer's (OEM) and supplier's (contract manufacturer) site.

The following diagram provides an overview of the general data flow from a business point of view. For more information about the data flow from a technical perspective, see Message Flow: Contract Manufacturing Procurement.

Business Data Flow: Contract Manufacturing Procurement

In the Contract Manufacturing Procurement business scenario, the customer can send purchase orders or purchase order updates to the SAP SNC system. The supplier can confirm the purchase order and send updates on component consumption. They can also send an ASN to inform the customer about an upcoming goods receipt.

If the supplier's system environment is able to create an ASN message, the supplier can send the ASN message to the SAP NetWeaver system. The ASN is then published on the SAP SNC system and contributes to the "stock in transit" quantities in the inventory monitor of the platform.
