Datasources are active but showing as "Not Executable"

Hi Gurus,

Recently we had a System Copy to our Source system.

After that all the Data sources in the BW production environment are showing as " Not Executable" and all the transfer structures are showing as inactive.

I have  tried replicating the datasources with the program RSDS_DATASOURCE_ACTIVATE_ALL and the transfer structures with the program RS_TRANSTRU_ACTIVATE_ALL  but still the problem hasn't fixed.

Can anyone help me on this...

Regards,

Latha
