Hi Raman, Thak you for your response.
The BW system is already connected to both systems: DEVCLNT100 and DEVCNTL100.
And I have already replicate the dataSources from both systems.
Now, When I have activated the InfoCube 0PS_C41, I have only the source system DEVCLNT100 selected, I have selected the option "in Data flow before", in fact all the 0PS_C41 infocube's DataSources were selected from the DEVCLNT100.
Now, I want that all those dataSource been replaced by those from the other system DEVCNTL100.
Thank's for your help.
