Problem using parameter IT_EVENT_EXIT of FM 'REUSE_ALV_GRID_DISPLAY'

Question

Hi,
I am working with FM 'REUSE_ALV_GRID_DISPLAY' .
Now when i am trying to use the parameter IT_EVENT_EXIT according to the FM documentation, its not responding accordingly.
I want that when i press the menu button for "DESELECT ALL' , i should be able to respond to the execution of the standard function before the ALV does it.
*&      Form  Z8_EVENT_EXIT
      text
-->  p1        text
<--  p2        text
form Z8_EVENT_EXIT .
DATA : L_EVENT_EXIT TYPE SLIS_EVENT_EXIT.
REFRESH R_EVENT_EXIT.
L_EVENT_EXIT-UCOMM = '&SAL'.
L_EVENT_EXIT-BEFORE = 'X'.
APPEND L_EVENT_EXIT TO R_EVENT_EXIT.
CLEAR R_EVENT_EXIT.
endform.                    " Z8_EVENT_EXIT
FORM Z8_PERFORM_ALV_GRID .
  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
   EXPORTING
   IT_EVENT_EXIT                     = R_EVENT_EXIT
ENDFORM.

Answer 1

In fact, you should use the 'USER_COMMAND' routine to put your code, not the 'EVENT'.
eg :
*       ITAB_user_command                                             *
FORM itab_user_command  USING ucomm TYPE sy-ucomm
                        s_selfield TYPE slis_selfield.
    WHEN '&IC1'.
*     Call Transaction MM03
      IF s_selfield-fieldname = 'MATNR' .
            READ TABLE itab INDEX s_selfield-tabindex.
            SET PARAMETER ID 'MAT' FIELD itab-matnr.
            SET PARAMETER ID 'WRK' FIELD itab-werks.
        CALL TRANSACTION 'MD04' AND SKIP FIRST SCREEN.
      ENDIF.
  ENDCASE.
ENDFORM. "ITAB_user_command
