Prerequisites
  1. You have made the following settings in the BW Customizing Implementation Guide, under SAP Business Warehouse → Connections to Source Systems.
    • General Connection Settings
    • Connection between flat files and BW system
    • Perform automatic workflow customizing
  2. As a rule, system changes are not permitted in productive systems. Connecting a system as a source system to a BW or connecting a BW to a new source system will, however, mean changes as far as the system change option is concerned. In the client used in the BW system, you have therefore made sure that the following changes are permitted during the source system connection:

    Cross-client Customizing and repository changes

In the BW Customizing Implementation Guide, select the relevant client under SAP Business Warehouse → Connections to Source Systems → General Connection Settings → Assign Logical System to Client, then choose Goto → Detail. In the Cross-Client Object Changes field, choose the Changes to Repository and Cross-Client Customizing Allowed option.

Changes to the local developments and Business Information Warehouse software components

You use transaction SE03 (Organizer Tools) to set the change options. Choose Organizer Tools → Administration → Set Up System Change Option. Choose Execute. On the next screen, make the following settings:.

Changes to the customer name range.

Again, you use transaction SE03 to set the change option for the customer name range.

Changes to BW namespaces /BIC/ and /BI0/

Again, you use transaction SE03 to set the change option for the BW namespaces.

Procedure
  1. In the source system tree in the Data Warehousing Workbench, choose Create in the context menu of the File folder.
  2. Enter the technical name of your file system under Source system and enter a description.
Result

In BW the ALE settings are created in the background that are necessary for communication between a BW system and a file system. The BW settings in BW are created to a new connection.
