Here is the procedure to handle TOP_OF_PAGE event in ALV GRID display.
- declare events table like this
data : i_events type slis_t_event, w_events like line of i_events. - Build events table
w_events-name = 'TOP_OF_PAGE' . w_events-form = 'TOP_OF_PAGE' . APPEND w_events TO i_events. CLEAR w_events. - Pass this events table through REUSE_ALV_GRID_DISPLAY.
- TOP_OF_PAGE call back should be like this in your case.
- Instead of all 1 and 2 steps you can just pass TOP_OF_PAGE the above subroutine through REUSE_ALV_GRID_DISPLAY in the exporting parameters.
*&---------------------------------------------------------------------* *& Form top_of_page *&---------------------------------------------------------------------* FORM top_of_page. DATA : li_header TYPE slis_t_listheader, w_header LIKE LINE OF li_header. w_header-typ = 'S'. w_header-info = g_var1. APPEND w_header TO li_header. CLEAR w_header. w_header-typ = 'H'. w_header-info = g_var2. APPEND w_header TO li_header. CLEAR w_header. w_header-typ = 'A'. w_header-info = g_var3. APPEND w_header TO li_header. CLEAR w_header. CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE' EXPORTING it_list_commentary = li_header. ENDFORM. " top_of_page
