LOOP AT SCREEN - MAKING SOME FIELD REQUIRED AND DYANMIC

Hi,

I have a report with 4 radio buttons and 10 i/o fields, when user clicks on each button 2 or 3 fields will be open for input and i have done the same using Loop at screen screen-input = 0 ....

I want to make the open fields as required to i achived by using SCREEN-REQUIRED = 1.

But my problem is I have to initialize the 1st radio button as default, so now 2 fields are open for input and it show those are required too. But if I am selecting the second radio button then i get a error message 'Please enter the required fields'.

Note: I am not executing,I am just selecting the second radio button, I have used Loop at screen in AT selection-screen output.

I tried to debug by clicking the second readio button but it does not go to debug mode, it just prompts the error message

I tried to clear the screen field required to 0 for those who have in At selection screen, but failed since it is not triggering.

Please help to solve this. I have already gone thru some of the Threads in SDN, It show to hide and so on via selecting the radio button, I want to remove the defauld or required from the screen fields when user clicks on the another radio button.

Points assured.

regards,

Prabhu
