Answer 1

I UNDERSTOOD Y U HAVE GIVE ERROR MESSAGE,
WHEN U R DECLARING THE VALUES AS OBLIGATORY BEFORE, THEN NO NEED TO GIVE MESSAGES IN AT SELECTION SCREEN.
BUT BASED ON SOME CONDITIONS, IF U WANT TO MAKE THEM OBLIGATORY DYNAMICALLY THEN GIVE THE CONDITION ALSO
EXAMPLE
AT SELECTION-SCREEN OUTPUT.
  LOOP AT SCREEN.
    IF a = 'X'.
      IF screen-group1 = 'GR2'.
        screen-input = 0.
             ELSE.
       SCREEN-INPUT = 1.
      ENDIF.
      MODIFY SCREEN.
    ENDIF.
    IF c = 'X'.
      IF screen-group1 = 'GR1'.
        screen-input = 0.
     ELSE.
       SCREEN-INPUT = 1.
      ENDIF.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.
AT SELECTION-SCREEN.
IF  d is initial.
MESSAGE e009.
ENDIF.
start-of-selection.
write b.
2ND EXAMPLE:
AT SELECTION-SCREEN OUTPUT.
  LOOP AT SCREEN.
    IF a = 'X'.
      IF screen-group1 = 'GR2'.
        screen-input = 0.
             ELSE.
       SCREEN-INPUT = 1.
      ENDIF.
      MODIFY SCREEN.
    ENDIF.
    IF c = 'X'.
      IF screen-group1 = 'GR1'.
        screen-input = 0.
     ELSE.
       SCREEN-INPUT = 1.
      ENDIF.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.
AT SELECTION-SCREEN.
IF B = 5 AND d is initial.
MESSAGE e009.
ENDIF.
start-of-selection.
write b.
I HAVE SENT U TWO EXAMPLES, IN THE SEOND EXMAPLE, IT WORKS FINE AS U HAVE GIVEN SOME OTHER CONDITION.
IN THE FIRST EXAMPLE, AS IT WILL NOT WORK AS IAM CHECKING ONLY INITIAL CONDITION.
FOR CHECKING ONLY INITIAL CONDITION, NO NEED TO WRITE IT AT SELECTION SCREEN , U CAN DIRECTLY DECLARE AS OBLIGATORY IN THE BEGINING IT SELF.
JUST COPY AND PASTE MY TWO PROGRAMS AND FIND OUT THE DIFFERENCE IAM EXPLAINING
