Selection field becomes invisible in ECC6

Hi,

Here is the issue:

I had developed new program in old version 4.7 long back. It was working fine on production system.

Then we upgraded from 4.7 to ECC6.

Now I did one modification in selection screen. Added one more field in selection screen.

It works fine in development and test system. But I am not able to see this field in production.

In program I can see the code for added field. If I execute selection screen separately, thats works fine too.

But when I call it with program I cant see this field.

Please reply me asap if somebody has faced same issues..

Thanks in advance.

Harshada.
