Answer 1

For example....
DATA: lo_alv_grid            TYPE REF TO cl_gui_alv_grid.
DATA: lo_form_alv_container  TYPE REF TO cl_gui_custom_container.
* Create Controls
    IF lo_form_alv_container IS INITIAL.  "<-- Check if already created
      CREATE OBJECT lo_form_alv_container
        EXPORTING
          container_name = 'FORMULA_CONTAINER'.
* Create control based ALV grid
      CREATE OBJECT lo_alv_grid
        EXPORTING
          i_parent = lo_form_alv_container.
* set for first display
      lo_alv_grid->set_table_for_first_display(
                EXPORTING
                   is_layout            = ls_layout
                   it_toolbar_excluding = lt_exclude
                CHANGING
                   it_outtab            = lt_formulas[]
                   it_fieldcatalog      = lt_fieldcat[] ).
    ELSE.
      lo_alv_grid->refresh_table_display( ).    "<-- If so, just refresh
    ENDIF.
