Same Master Data from different Source Systems

Hi to all,

I have a problem concerning same master data from different Sap R/3 source systems.

For example is the customer (based on 0Customer) "123456" in the first source system named "Maier" and in the second source systems named "Schmidt". When I load the master data for 0Customer, BW overwrites this customer with the datas of the actual source system.

For my source systems I have already assigned different Source System IDs.

Is there a solution to use only one InfoObject for the Master Data of 0Customer from the different source systems?

Many thenks and best regards

Jörg
