Transaction Code Problem

Hi All,

I have just created a TCODE in the DEV. The TCODE works fine in DEV.

Then, I did a transport of the TCODE from DEV to QAS for testing.

However, when the TCODE reaches the QAS, it is not working.

The program's screen came out but when i click Execute it just closes and return the SAP main screen.

Then i run the program in SE38 but its working fine.

Why the TCODE is not running properly in QAS after transport from DEV?

Can anyone help?

Thanks

William
