Modify Selection screen
On my selection screen.
I have two parameters
Param1 , Obligatory
and then two radio buttons
My requirement is if i select one radio button param 1 is mandatory
and if i select radiobutton 2 then param1 is not required.it should be grayed out.
When i tried to modify the screen in at selection-screen output
when ever i am selecting second radio button on the selection sreen i am getting a message asking for input for param 1..
