BW - SAP Source system configuration

[JAMpe]

Hello Everyone,

I 've got some questions regarding the configuration of a SAP Source system in RSA (BW). According to the configuration guide you need to do the following steps in the Source system before connecting both sytems (BW & SAP NW ABAP):

• Cross-client Customizing and repository changesIn the implemenation guide, under SAP NetWeaver Application Server IDoc Interface / Application Link Enabling (ALE) Basic Settings Logical Systems Assign Logical System to Client , select the relevant client and choose Goto Detail .In the Cross-Client Object Changes field, choose the Changes to Repository and Cross-Client Customizing Allowed option.
• Changes to the software components Local Developments(LOCAL) and SAP NetWeaver BW(SAP_BW)In the Transport Organizer Tools (Transaction SE03) choose Administration Set System Change Option and then Execute. In the next screen mark the software componentsLOCALandSAP_BWaschangeable.
• Changes to the customer name range.In the Transport Organizer Tools (Transaction SE03) choose Administration Set System Change Option 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 Administration Set System Change Option and then Execute. On the next screen, mark the BW namespaces with the prefixes/BI0/and/BIC/as changeable

Apart form the RFCs and system users created, what else does this configuration do? Is there some customizing (client-dependant or closs client) or repository objects changed? Are theses steps documented somewhere? Lets' assumed that I'm done with this source system (NW ABAP), is there a way to reverse this configuration? I mean, like It was before the connection to BW.

Best regards,

Jam

Hi Jam

During the configuration time it will replacate the configuration into BI data warehouse

You can refer the SCN links with detailed steps with snapshot.

When you create a source system from Tx RSA1 in a BW system it basically creates entries in few configuration tables in addition to the RFC connection. Also the partner profiles and EDI ports as used here. As far as I know it does not do any repository modifications and to revert the configuration you need to delete the source system from the BW system. Probably a BW consultant can give you a better explanation on this.
