set_table_for_first_display don't work

Create container object...


CREATE OBJECT cnt_0100
      EXPORTING
        container_name = 'CNT_0100'
      EXCEPTIONS
        OTHERS         = 1.

Done..

Create alv object ...


 CREATE OBJECT alv_0100
      EXPORTING
        i_parent = cnt_0100
      EXCEPTIONS
        OTHERS   = 1.

Done...

Call Method..


CALL METHOD alv_0100->set_table_for_first_display
     EXPORTING
       i_default                     = 'X'
       i_save                        = 'A'
       is_layout                     = layout
       it_toolbar_excluding          = it_excluding[]
       is_variant                    = gs_variant

     CHANGING
       it_outtab                     = gt_result
       it_fieldcatalog               = p_it_fcat

     EXCEPTIONS
       invalid_parameter_combination = 1
       program_error                 = 2
       too_many_lines                = 3
       OTHERS                        = 4.

Done...

And nothing ...

Mistake was because i didn't create container CNT_0100 in screen (SCREEN -> FORMAT)
