SAP BW Extraction Through Open Hub Destination Overview

SAP BW Extraction Through Open Hub Destination Overview

You can use the Open Hub Destination (OHD) to extract data from SAP BW. If you extract data through SAP BI version 7.0, you can extract through the open hub destination. The open hub destination is an independent object that you can integrate into the data flow. You can configure InfoCubes, DataStore Objects, InfoObjects, and InfoSets as open hub data sources.
The following figure shows how PowerCenter extracts data:
""
PowerCenter data extraction from SAP BW occurs in the following sequence:
  1. A process chain directs an open hub destination to extract data. The process chain can also help you identify the point of failure in case of a system failure.
  2. Use the ZPMSENDSTATUS ABAP program or pmsaputil to configure the third-party parameters. Use pmsaputil to start the process chain.
  3. The open hub destination extracts data and loads it to a into a database table in the BW system.
  4. The open hub destination notifies the RFC destination that is specified in the open hub destination that data extraction is complete.
  5. The SAP BW Service initiates the PowerCenter workflow that the Integration Service uses to extract data from SAP BW.
  6. The Integration Service extracts data from the SAP BW
When the data extraction begins, you can view log events to track the interactions between PowerCenter and SAP BW.
