Hi Shyam,

SAP recommends to add a new radiobutton, say "none", that is checked by default. Then the user has to check one of the other two radiobuttons.

Also remember to group these 3 radiobuttons together, so that the user only checks one of them.

I hope it helps. Kind regards,

Alvaro

Hi shyam ,

Do as I say

Now u have 2 Radiobuttons on ur screen say R1 and R2

on the screen layout give the description to both of them .

Now select both R1 and R2 with their descriptions .

and right click on the selected area now at the end of the window which has come out of the right click just click on the option called define radio button group or something like that .

Now u have radiobutton group defined now when u execute the t-code u wont find both the buttons selected .

Thanks

Sahil

Hello,

Radio buttons are generally used to select only one option of a list. so by default one and only one of the radio button will be selected, then user can select any other radio button which will unselect any other radio button which is selected.

Now your problem is that both the radio buttons are selected, to avoid that you have to group both the radio buttons together.

Select the radio buttons and right click and select group. this group the radio buttons. and only one will be selected at time.

Dear Shyam,

To the best of my knowledge,

As per the SAP architecture at least one radio button is selected even you clear the value in PBO.

This is not possible to have all the radio buttons deselected ( one radio button is selected by default).

This is the same in any programing languages that support radio buttons (This is to the best of my knowldge)

if your problem is solved please close this thread

Best Regards

Any ideas about the error message "invalid field format(screen error)" on the screen with the radio buttons?
