Multiple BW system One SAP ECC sourcesystem

[former_member302630]

Hi,

My client has planned to connect 3 SAP BW systems to one ERP system. I am wondering how to solve maintaining datasources deltas for 3 BW systems in one ECC system.

Is there any how to.. document for multiple BW systems to one SAP ECC system? how to connect and maintain deltas and extraction logic for multiple BW systems?

Regards,

Cleo

Hi Cleo,

Basically the RSA7 delta is capable of multiple connected BW systems. Logical System is identifying the different delta queues for the same DataSource. However, you have to be careful with parallel extraction by the two BW systems because they could interfere in case of timestamp delta mechanism (as is the case for DataSource 0FI_GL_14). Please refer to the following SAP Notes for more information:

• SAP Note 775568 - Two and more BW systems against one OLTP system;
• SAP Note 844222 - Two OR more BW systems against one OLTP system.

Best regards,

Sander
