Are you doing this in the AT SELECTION-SCREEN OUTPUT event? If not, try it there.

AT SELECTION-SCREEN OUTPUT.

loop at screen.
      check screen-name  cs 'REF_VP'.
       screen-input = 0.
       modify screen.
 endloop.

Regards.

If you have created only one element in that screen then you can see only one entry in the screen table. Try to create checkbox / pushbutton so that you can see multiple entries in the screen table.

you should write this at selection screen event.

What you can do to check is debug it.

before entering the value press /h in command and then enter value to see if your loop at screen gets triggered. This way you will understand where to code the loop at screen.
