many times we are doing modification..

so the modification had been done withe use of Screen
Structure.

Answer / saravanan

At selection-screen output triggers before the actual
display of the list. So, when u press ENTER button, 'Loop
at screen' written under the event gets triggered. And u
can set the screen parameter 'INVISIBLE' of the
corresponding field to '1'. This is how it works!
