Hide parameter / select option in selection screen

We can Hide parameter / select option in selection screen dynamically by manipulating screen object.

SCREEN is like an internal table with a header line. However, you do not have to declare it in your program. Go to debugging mode and then view structure of screen.

You can modify SCREEN in your ABAP program during the PBO event of a screen. Its contents override the static attributes of the screen fields for a single screen call. The only statements that you can use with SCREEN are:


LOOP AT SCREEN.
...
MODIFY SCREEN.
...
ENDLOOP.

We can hide parameter by set screen-active to 0.
Here is example of how to hide parameter in selection screen. Write it, and change click on radiobutton to hide parameter.
