Background Execution Problem-Docking Container with 2 ALV Grids in one scre

Question

Hi Friends,
I have created 2 ALV Grids in one screen - one below another using DOCKING CONTAINER.
The objects are 'g_dock_cont' and 'g_dock_cont1'.
I am getting the foreground output as expected with 2 ALV Grids.
While executing in background (F9), I am getting only output of first ALV grid. Second ALV is not getting displayed in BACKGROUND(F9) mode.
How to solve this.
FORM create_objects.
* Materials with data
  IF   g_dock_cont IS INITIAL.
   IF sy-batch NE 'X'.
*CREATE THE OBJECT FOR DOCKING CONTAINER
    CREATE OBJECT g_dock_cont
      EXPORTING
        side                  = cl_gui_docking_container=>dock_at_top
        extension             = 300.
    ENDIF.
*CREATE THE OBJECT FOR ALV GRID
    CREATE OBJECT g_alvgrid
           EXPORTING i_parent = g_dock_cont.
    wa_layout-grid_title =
          'Materials with Data'.
  ENDIF.
IF NOT I_DETAIL[] IS INITIAL.

Hi,
What i was saying is that you need to code again for background mode of execution.
AT END OF SELECTION.
IF SY-BATCH EQ 'X'.
  PERFORM DISPLAY1.
  PERFORM DISPLAY2.
In DISPLAY1 use REUSE_ALV_LIST_DISPLAY to display data from outtab1.
In DISPLAY2 use REUSE_ALV_LIST_DISPLAY to display data from outtab2.
For example : execute this report in background mode.this will not execute in online mode.
After execution you will get two spools one for KNA1 and one for LFA1 data. Spool can be controlled via IS_PRINT structure.
report  zrbackground.
data gt_lfa1 type standard table of lfa1.
data gt_kna1 type standard table of kna1.
start-of-selection.
  select * from lfa1 into table gt_lfa1 up to 10 rows.
  select * from kna1 into table gt_kna1 up to 20 rows.
end-of-selection.
  if sy-batch eq 'X'.
    perform display_lfa1.
    perform display_kna1.
  endif.
*&      Form  DISPLAY_LFA1
      text
-->  p1        text
<--  p2        text
form display_lfa1 .
  call function 'REUSE_ALV_LIST_DISPLAY'
    exporting
      i_callback_program = sy-repid
      i_structure_name   = 'LFA1'
    tables
      t_outtab           = gt_lfa1
    exceptions
      program_error      = 1
      others             = 2.
  if sy-subrc <> 0.
    message id sy-msgid type sy-msgty number sy-msgno
            with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  endif.
endform.                    " DISPLAY_LFA1
*&      Form  DISPLAY_KNA1
      text
-->  p1        text
<--  p2        text
form display_kna1 .
  call function 'REUSE_ALV_LIST_DISPLAY'
    exporting
      i_callback_program = sy-repid
      i_structure_name   = 'KNA1'
    tables
      t_outtab           = gt_kna1
    exceptions
      program_error      = 1
      others             = 2.
  if sy-subrc <> 0.
    message id sy-msgid type sy-msgty number sy-msgno
            with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  endif.
endform.                    " DISPLAY_KNA1
Please let me know if its not clear or you need more info.
Thanks,
Abhishek
