Data source transports in BW

Hi All,

From ECC Dev to ECC Quality i moved TR and success, after that i replicated Data source from ECC Q to BW Q went fine. after that i am unable actiavte data source in BWQ. active icon was disabled, but by using program i can manage. but just need to know is this normal behaviour?

Next i planned to move BW D data source to BWQ, this may over writes and active version? is this way works?? i have further TRs which are Cube, transformations, info pak and DTP.

About objects no problm all r existed in all environments.

am using BW 7.3. am bit kind new to TR.

Thanks
