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.

[Former Member]

when i click append button it doesn't trigger the user command  but  data changed finished.

Hi Lyam,

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

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.
