Ritesh,
Go through the code .Here instead of input fields you add the modi id for BUTTONS.give same MODIF ID name to required enable fields and not required fileds are another group name.
PARAMETERS: p_pcfile LIKE rlgrap-filename OBLIGATORY DEFAULT 'C:\'
            MODIF ID ccc,
            p_pctype LIKE rlgrap-filetype OBLIGATORY DEFAULT 'ASC'
            MODIF ID ccc,
            p_unix   LIKE rlgrap-filename OBLIGATORY DEFAULT '.\'
            MODIF ID ccc.
PARAMETERS: p_dir LIKE rlgrap-filename OBLIGATORY DEFAULT '.'
            MODIF ID ddd,
            p_fp  LIKE rlgrap-filename
            MODIF ID ddd.
AT SELECTION-SCREEN
AT SELECTION-SCREEN OUTPUT.
  IF p_up = 'X' .
    LOOP AT SCREEN.
      CASE screen-group1.
        WHEN 'CCC'.
          screen-input = 1.  "Enable
          screen-invisible = 0. "Disable
          MODIFY SCREEN.
        WHEN 'DDD'.
          screen-input = 0.
          screen-invisible = 1.
          MODIFY SCREEN.
      ENDCASE.
    ENDLOOP.
  ENDIF.
  IF p_list = 'X'.
    LOOP AT SCREEN.
      CASE screen-group1.
        WHEN 'CCC'.
          screen-input = 0.
          screen-invisible = 1.
          MODIFY SCREEN.
        WHEN 'DDD'.
          screen-input = 1.
          screen-invisible = 0.
          MODIFY SCREEN.
      ENDCASE.
    ENDLOOP.
  ENDIF.
