CRM-BW Integration 
The integration between SAP CRM and SAP BW forms the basis for the analytical applications delivered with mySAP CRM Analytics. It is characteristic of an analytical application to enable data to be exchanged in a closed loop scenario between operational and analytical areas that are not necessarily in the same system. The CRM-BW integration makes it possible for data to be exchanged in both directions between analytical SAP BW and operational SAP CRM. On the one hand, therefore, you can extract data from SAP CRM (or any other SAP source system) into SAP BW. On the other hand, you can also transfer under certain conditions from SAP BW into SAP CRM different types of data that was collected in SAP BW from various systems (such as SAP CRM, SAP R/3, or third-party systems) and possibly even processed there as well (for example, using the data mining tools). If, for example, you want to transfer information on business partners, this data must already exist in SAP CRM.
The extraction of data from SAP CRM into SAP BW works in exactly the same way as data extraction from any other SAP source system into SAP BW. For information about data extraction, see the documentation in the SAP Library for SAP BW, which covers for example the following topics:
· Connecting the source system (under Administrator Workbench ® Modeling ® Source System ® Creating an SAP Source System)
· Background information on data extraction (under Administrator Workbench ® Modeling ® Source System ® Data Extraction from SAP Source Systems)
· Transferring delivered Business Content (under Administrator Workbench ® Business Content (Versions) ® Installing Business Content)
· Executing the data transfer (under Administrator Workbench ® Administration ® Scheduler)
In the Implementation Guide (IMG), you perform the
settings that need to be made in SAP CRM for the data extraction. The IMG
provides you with some general IMG activities that exist in each SAP system
able to extract data into SAP BW. You find these general IMG activities in CRM
Customizing under Integration with mySAP.com Components
® Business Information
Warehouse. In the subnode Settings for Application-Specific
DataSources (CRM) that you find here, you can also make CRM-specific settings, such
as those for the BW Adapter. The BW Adapter provides a uniform structure for
the DataSources in SAP CRM and collects the data to be extracted. For more
information, see the documentation accompanying the respective IMG activities
in the IMG. You can also see the section
The BW Adapter.
You have various options for transferring data from SAP BW into SAP CRM.
