Hi...
Dont Declare your field as OBLIGATORY.
Instead perform the validation in AT SELECTION-SCREEN event. But validation should be only when Particular Radiobutton is selected.
And Generate only Error Message (Type E).
Try this code:
AT SELECTION-SCREEN on <yOUR mandatory field>.
   IF PA_UPD = 'X'.
         IF <YOUR MANDATORY FIELD>  IS INITIAL.
              Message 'Entry is must in this field' type 'E'.
         ENDIF.
   ENDIF.
AT SELECTION-SCREEN OUTPUT.
IF pa_udp = 'X'.
LOOP AT SCREEN.
IF screen-group1 = 'ABC'. "#CCE
screen-active = 1.
ELSEIF screen-group1 = 'DEF'.
screen-input = 0.
ENDIF.
MODIFY SCREEN.
ENDLOOP.
ELSEIF pa_rep = 'X'.
LOOP AT SCREEN.
IF screen-group1 = 'ABC'. "#CCE
screen-input = 0.
ELSEIF screen-group1 = 'DEF'.
screen-active = 1.
ENDIF.
MODIFY SCREEN.
ENDLOOP.
ENDIF.
