Configurations in BWLocate this document in the navigation structure

Use

Make the settings in BW described below for each SAP source system you want to connect to the BW system in order to transfer data.

IMG Settings for Connecting to Other SAP Systems

In the Implementation Guide (IMG) under Start of the navigation path SAP NetWeaver Next navigation step Business Warehouse Next navigation step Connections to Other Systems End of the navigation path make the following settings:

  • General connection settings

    • Define logical system

    • Assign logical system to client

  • Perform automatic workflow Customizing

Settings for Background Users

Background Users in BW

The background user in BW is used for communication with the BW source systems, for the extraction of data, and for background processes in BW.

In the Implementation Guide (IMG), under Start of the navigation path SAP NetWeaver Next navigation step Business Warehouse Next navigation step Automated Processes End of the navigation path, create the background user for background processes in BW and assign the profile S_BI-WHM_RFC to the user.

Make sure that the background user in BW is used as the default setting when creating the source system. Check that the background user is entered in the Data Warehousing under Start of the navigation path Settings Next navigation step Global Settings End of the navigation path in the field BW User for ALE.

Proposal for Background Users in the Source System

The background user in the source system is used for communication with BW and for the extraction of data.

In the Implementation Guide (IMG), under Start of the navigation path SAP NetWeaver Next navigation step Business Warehouse Next navigation step Connections to Other Systems Next navigation step Connections Between SAP Systems and BI System End of the navigation path, enter a suggestion for the name of the background user in the source system.

The name that you enter here is displayed by default as the background user in the dialog for creating the source system. This name is also used to generate the user (if it does not already exist) when creating the source system. If a suitable user with the profile S_BI-WX_RFC exists in the source system, enter this user here.

Note

If the source system you are using is also a BW system, SAP recommends that you create the background user for BW and the background user for the (BW) source system completely separately.

You can use the same user in both roles for the Myself extraction. In this case, we recommend that you also assign the profile S_BI-WX_RFC to the background user in BW.

Settings for the System Change Option

As a rule, system changes are not permitted in productive systems. Connecting a system as a source system to a BW system or connecting a BW system to a new source system will, however, mean changes as far as the system change option is concerned. Make the following settings in the BW system to ensure that the following changes are valid in the relevant clients of the systems when connecting the source system.

  • Cross-client Customizing and repository changes

    In the Implementation Guide under Start of the navigation path SAP NetWeaver Next navigation step Business Warehouse Next navigation step Links to Other Source Systems Next navigation step General Connection Settings Next navigation step Assign Logical System to Client End of the navigation path, select the relevant client and select Start of the navigation path Goto Next navigation step Detail End of the navigation path.

    Choose the entry Changes to Repository and Cross-Client Customizing Permitted in the field Changes to Cross-Client Objects.

  • Changes to the software components Local Developments ( LOCAL) and SAP NetWeaver BW ( SAP_BW)

    In the Transport Organizer Tools (Transaction SE03) choose Start of the navigation path Administration Next navigation step Set System Change Option End of the navigation path and then Execute. In the next screen mark the software components LOCAL and SAP_BW as changeable.

  • Changes to the customer name range

    In the Transport Organizer Tools (Transaction SE03) choose Start of the navigation path Administration Next navigation step Set System Change Option End of the navigation path and then Execute. In the next screen mark the customer namespace as changeable.

  • Changes in the BW namespaces with prefix /BI0/ (SAP namespace) and /BIC/ (customer namespace)

    In the Transport Organizer Tools (Transaction SE03) choose Start of the navigation path Administration Next navigation step Set System Change Option End of the navigation path and then Execute. On the next screen, mark the BI namespaces with the prefixes /BI0/ and /BIC/ as changeable.
