HAI,

It seems your internal table is empty..Debug and see whether it has any records or not.

HAI,

You can also create an ALV with out field catalog. Try commenting the field catalog and see.

See this tutorial. There are two scenarios explained:

Was custom container created correctly? Did you place ALV in your custom container? See below

DATA: r_cc_container TYPE REF TO cl_gui_custom_container.
DATA: r_alv_grid TYPE REF TO cl_gui_alv_grid.

DATA: it_sflight TYPE TABLE OF sflight,

INITIALIZATION.
  SELECT * FROM sflight INTO TABLE it_sflight UP TO 10 ROWS.

  CALL SCREEN 100.

MODULE pbo_0100 OUTPUT.
"create container
  CREATE OBJECT r_cc_container
    EXPORTING
      container_name    = 'CUSTOM_CONTROL'.

"create alv grid placing in custom container
  CREATE OBJECT r_alv_grid
    EXPORTING
     i_parent           = r_cc_container.

"dispaly the output
  CALL METHOD r_alv_grid->set_table_for_first_display
    EXPORTING
      i_structure_name              = 'SFLIGHT'  "pass table strcuture...
    CHANGING
      it_outtab                     = it_sflight

ENDMODULE.

Hi,

Please check if object of ALV Grid where u assign Container is initial than only call call method gr_alvgrid->set_table_for_first_display else if ALV Gird Object is not initial than call method gr_alvgrid->refresh_table_display.

e.g.

 if gr_alvgrid is initial.

  create object gr_ccontainer
    exporting
      container_name              = 'CC_ALV'
    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 e000 with 'Unable to get container to display list'.
  endif.


  create object gr_alvgrid
    exporting
      i_parent          = gr_ccontainer
    exceptions
      error_cntl_create = 1
      error_cntl_init   = 2
      error_cntl_link   = 3
      error_dp_create   = 4
      others            = 5.
  if sy-subrc <> 0.
    message e000 with 'Unable to instantiate list'.
  endif.

  call method gr_alvgrid->set_table_for_first_display
    exporting
      is_variant                    = wa_variant
      i_save                        = 'A'
      is_layout                     = gs_layout
    changing
      it_outtab                     = gt_final[]
      it_fieldcatalog               = gt_fieldcat[]
    exceptions
      invalid_parameter_combination = 1
      program_error                 = 2
      too_many_lines                = 3
      others                        = 4.
  if sy-subrc <> 0.
    message e000 with 'List could not be displayed'.
  endif.

elseif  not gr_alvgrid is initial .

  call method gr_alvgrid->refresh_table_display
    exceptions
      finished = 1
      others   = 2.
  if sy-subrc <> 0.
    message e000 with 'List could not be refreshed'.
  endif.
