Hi,

Did you write the following code sequence in PBO?

MODULE load_data OUTPUT.

  CREATE OBJECT c_container
    EXPORTING
      container_name              = 'C_CONTAINER'
    EXCEPTIONS
      cntl_error                  = 1
      cntl_system_error           = 2
      create_error                = 3
      lifetime_error              = 4
      lifetime_dynpro_dynpro_link = 5
      OTHERS                      = 6.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
               WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

  CREATE OBJECT grid
    EXPORTING
      i_parent          = c_container
    EXCEPTIONS
      error_cntl_create = 1
      error_cntl_init   = 2
      error_cntl_link   = 3
      error_dp_create   = 4
      OTHERS            = 5.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
               WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

  DATA:
      r_event TYPE REF TO lcl_event_receiver.
  CREATE OBJECT r_event.
  SET HANDLER : r_event->handle_double_click FOR grid,
                lcl_event_toolbar=>handle_toolbar FOR grid,
                lcl_event_toolbar=>handle_user_command FOR grid,
                r_event->handle_col FOR grid,
                r_event->handle_sort FOR grid.


  CALL METHOD grid->set_table_for_first_display

      is_layout                     = gs_layout

      it_fieldcatalog               = t_fcat
    EXCEPTIONS
      invalid_parameter_combination = 1
      program_error                 = 2
      too_many_lines                = 3
      OTHERS                        = 4.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
               WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

ENDMODULE.                             " LOAD_DATA  OUTPUT

Just check if grid is been passed container.
