Hello Johnny Jones,
1. Pass all function codes in it_exlcude internal table if you are using FM REUSE_ALV_GRID_DISPLAY.
Example :
wa_exclude-fcode = Function code.
APPEND wa_exclude TO it_exclude.
CLEAR wa_exclude.
2.If you are using class cl_gui_alv_grid(set_table_for_first_display) then fill the structure is_layout -no_toolbar = 'X' .
Thanks
