i want to do things as following code with FM
data: gr_display type ref to cl_salv_display_settings.
now my code structure is
call function 'REUSE_ALV_GRID_DISPLAY'
and i try call function 'REUSE_ALV_CMMENTARY_WRITE' which doesn't work as set_list_header. i think gui_title is not efficient because i have to set it again after alv display.
