Hi,

DATA : g_t_events TYPE slis_t_event.
DATA : g_r_events TYPE slis_alv_event.

    * Top of Page event for standard header

g_r_events-name = 'TOP_OF_PAGE'.
g_r_events-form = 'TOP_OF_PAGE'.
APPEND g_r_events TO g_t_events.

NOW u call the REUSE_ALV_LIST_DISPLAY.

Some thing like this

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = IT_VARIANT-REPORT
I_CALLBACK_TOP_OF_PAGE = 'TOP_OF_PAGE' IT_FIELDCAT = IT_FIELDCAT
I_SAVE = 'A'
IS_VARIANT = IT_VARIANT
TABLES
T_OUTTAB = G_T_OUTTAB
EXCEPTIONS
PROGRAM_ERROR = 1
OTHERS = 2.

IF SY-SUBRC 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.

&---------------------------------------------------------------------
*& Form TOP-OF-PAGE
&---------------------------------------------------------------------

    * For Top of page

----------------------------------------------------------------------
FORM TOP_OF_PAGE. "#EC CALLED

CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE'
EXPORTING
IT_LIST_COMMENTARY = IT_COMMENTARY.

ENDFORM. "top_of_page

Hi Michael,

what is it you want to achieve?

TOP_OF_LIST is triggered automatically and once per FM call before the first line of output is created.

The only way to trigger TOP_OF_LIST is to create any output. Even if the display table is empty, it will trigger TOP_OF_LIST .

Clemens

Hi Michael,

as I tried to explain: Just call FUNCTION 'REUSE_ALV_GRID_DISPLAY' and TOP_OF_LIST is raised (thrown).

Once again: What do you want to do?
