Hi,
if you want to gray out radio buttons after interactiing with selection screen then use following logic.
selection-screen: begin of block b0 with frame title text-000.
select-options so_vnum for lfa1-lifnr.
parameters: r1 radiobutton group rad1 modif id ABC default 'X',
            r2 radiobutton group rad1  modif id ABC,
            r3 radiobutton group rad1  modif id ABC.
parameters: p_numdys type char4.
selection-screen end of block b0.
AT SELECTION-SCREEN.
AT SELECTION-SCREEN OUTPUT.
IF P_NUMDYS IS NOT INITIAL.
LOOP AT SCREEN.
IF SCREEN-GROUP1 = 'ABC'.
SCREEN-INPUT = 0.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
ENDIF.
