Header for 'ZFI_ITEMS_DISPLAY'

Question

Hi,
   I have made function module similar to "FI_ITEMS_DISPLAY"  as 'ZFI_ITEMS_DISPLAY'  .... As output is coming in ALV...can anybody tell me how to write for the Header of this alv report.... In normal alv  we use to pass exporting parameter i_callback_top_of_page   = 'TOP-OF-PAGE'  in 'REUSE_ALV_GRID_DISPLAY' .. Is there anything similar over here

Hi Kumar,
as you did not say very clear what you did this is not easy to answer.
If your ZFI_ITEMS_DISPLAY was created by copying function group FI_ITEMS with FI_ITEMS_DISPLAY as ZFI_ITEMS_DISPLAY then you just need to populate the FORM routines TOP_OF_LIST, TOP_OF_PAGE  and USER_COMMAND.
In FI_ITEMS_DISPLAY they do not use exporting parameter i_callback_top_of_page but parameter it_event_exit            = gt_event_exit. gt_event_exit is pouplated in form alv_events_make. Here the internal eventnames are connected to FORM routines.
The code lines could be reduced by 2 thirds but many programmers behave as if payed by line.
Before asking questions some online help may have answered the question. In SE37 function builder there are green buttons for documentation of the IMPORT parameters. Documentation of I_CALLBACK_USER_COMMAND refers to parameter IT_EVENTS, here the documentation has it all.
