How to add Change Layout Button to ALV Toolbar?

Question

Hi All,
I am using a SAP GUI STATUS 'STANDARD' that has almost all the funcationality needed except for the change layout button.
I have tried changing the GUI STATUS to 'STANDARD_FULLSCREEN' which has the button I am looking for but it does not show up.
What am I missing to have the 'Change Layout' Button show on the toolbar?
thank you

I am using Classes.
I did not specify any type of table of 'exclude' buttons.
here is my code that display the ALV
DATA gr_alv TYPE REF TO cl_salv_table.
DATA gr_functions TYPE REF TO cl_salv_functions_list.
DATA gr_selections TYPE REF TO cl_salv_selections.
DATA gr_events TYPE REF TO cl_salv_events_table.
DATA gr_settings TYPE REF TO cl_salv_display_settings.
DATA gr_layout TYPE REF TO cl_salv_layout.
  TRY.
      cl_salv_table=>factory(
       IMPORTING r_salv_table = gr_alv
       CHANGING  t_table      = gt_rpt_details ).
      PERFORM f_display_settings.
      gr_alv->set_screen_status(
      "pfstatus = 'Z_STANDARD'
      pfstatus = 'ZSTANDARD_FULLSCREEN'
      report = sy-repid
      "i_save = 'A'
      set_functions = gr_alv->c_functions_all ).
      gr_events = gr_alv->get_event( ).
      "create layout object
      CREATE OBJECT gr_layout.
      gr_layout->get_current_layout( ).
      CREATE OBJECT event_handler.
      SET HANDLER event_handler->on_user_command FOR gr_events.
      gr_functions = gr_alv->get_functions( ).
      gr_functions->set_all('X').
      gr_functions->set_group_filter( value = if_salv_c_bool_sap=>false ).
*       Set print preview
      gr_functions->set_print_preview( ).
      gr_alv->get_display_settings( ).
      gr_alv->display( ).
