Copied Transaction ZCS02 not working...

Hi,

I want to create a copy of transaction CS02. But this is a function Group (CSDI).. After all, i copy the Function Group with all Function Modules. Also create a t.code ZCS02 through SE93 (copy program SAPMC29S also).

But, when i m executing the ZCS02 transaction, it's not working..means not responding.

Please tell me what would be the problem..

Regards,
