Within a radiobutton group, exactly one radiobutton must be set on. You can not have a radiobutton group which has no default. It is simply not possible in ABAP.

Why not use checkboxes instead?

Exactly, you can simulate the radiobutton functionality using checkboxes and when using checkboxes, no default is required. See the example.



REPORT zrich_0001.



PARAMETERS: p_check1 AS CHECKBOX USER-COMMAND check,
            p_check2 AS CHECKBOX USER-COMMAND check,
            p_check3 AS CHECKBOX USER-COMMAND check.

DATA: cursorfield(20) TYPE c.

AT SELECTION-SCREEN.


  GET CURSOR FIELD cursorfield.

  IF cursorfield = 'P_CHECK1'.
    p_check2 = space.
    p_check3 = space.
  ELSEIF  cursorfield = 'P_CHECK2'.
    p_check1 = space.
    p_check3 = space.
  ELSEIF cursorfield = 'P_CHECK3'.
    p_check1 = space.
    p_check2 = space.
  ENDIF.

Hi Surya,

One way could be you can hide the unselected second selection block.

two selection block a01 and a02. There are two radio button (p_r1, p_r2) in a1.

If p_r1 is choosed, selection block a02 is not  displayed; 
if p_r2 is choosed, selection block a02 is  displayed.

selection-screen: begin of block a01 with frame.
parameters: p_r1 radiobutton group rg1 default 'X' user-command uc,               
                  p_r2 radiobutton group rg1.
selection-screen: end of block a01.
 
selection-screen: begin of block a02 with frame.
selection-screen: begin of line,
pushbutton 33(20) selp user-command sel modif id chk ,
comment 55(13) selcnt  modif id chk,
end of line.
*SELECTION-SCREEN: SKIP.
parameters: p_count type i  modif id chk .
selection-screen: end of block a02.
 
 
at selection-screen output.
 
  if p_r1 = 'X'.
    loop at screen .
      if screen-group1 = 'CHK'.
        screen-active = 0.
        modify screen.
      endif.
    endloop.
  endif.
