Configurations in BW

IMG Settings for Connecting to Other SAP Systems

In the Implementation Guide (IMG) under SAP NetWeaver  Business Warehouse  Connections to Other Systems 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 SAP NetWeaver  Business Warehouse  Automated Processes, 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 Settings  Global Settings 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 SAP NetWeaver  Business Warehouse  Connections to Other Systems  Connections Between SAP Systems and BI System, 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.

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 SAP NetWeaver  Business Warehouse  Links to Other Source Systems  General Connection Settings  Assign Logical System to Client, select the relevant client and select Goto  Detail.

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