To consume data from SAP business content, you define PowerCenter as a logical system in SAP. The logical system enables the PowerCenter Integration Service to initiate tasks within SAP. For example, the PowerCenter Integration Service connects to SAP as a logical system when you create a mapping to process a DataSource. It also connects to SAP as a logical system during a PowerCenter session to request data from the SAP system. Create a logical system in SAP for business content integration before you create a mapping to process a DataSource.
