Hi Lyam,

Can you try write CALL METHOD cl_gui_cfw=>set_new_ok_code('REFRESH'). instead of CALL METHOD ALV1->REFRESH_TABLE_DISPLAY in METHOD handle_user_command.

You shouldn't be able to "intercept" the function code in event user_command, better handle event before_user_command, there add your own code and reset function code to space with method set_user_command.

Hint: For reference see Changing Standard Functions.

Raymond

Hi Lyam,

are you sure add button to ALV TOOLBAR. If button is at Screen Toolbar, you have to use PAI module.
