Two ALV Grids in Single Screen using OOPs

In a report we can create two ALV grids in a single screen by using two Custom Container in one screen. Here we shall have a standard screen (like screen 0100 or 1000). We must not modify that screen. We shall create a custom screen (screen 9000 or 9001), since custom screen number starts from 9000. 

After that we shall go to the LAYOUT of screen 9000. There we shall make two containers by drag and drop as following.



Now in PBO block we shall make custom PF status and custom title. Then after we shall create object for Container 1 and Container 2 which are referred to CL_GUI_CUSTOM_CONTAINER

CODE: 
  CREATE OBJECT ob_custom1
    EXPORTING
      container_name = 'CONTAINER1'.

  CREATE OBJECT ob_custom2
    EXPORTING
      container_name = 'CONTAINER2'.

After that ALV Grid 1 and Grid 2 objects shall be created for Container 1 and 2. The Grids are referred to CL_GUI_ALV_GRID. Here we shall assign grid 1 for container 1 by exporting i_parent to the specific container. Similarly grid 2 for container 2 must be assigned by exporting i_parent to container 2. 

CODE:
  CREATE OBJECT ob_grid1
    EXPORTING
      i_parent = ob_custom1.

  CREATE OBJECT ob_grid2
    EXPORTING
      i_parent = ob_custom2.

After that Grid method SET_TABLE_FOR_FIRST_DISPLAY must be called with changing parameters. Here we have used field catalog (it_fieldcatalog) for selected custom fields and output table (it_outtab) for specific output table (Internal Table).

CODE:
  CALL METHOD ob_grid1->set_table_for_first_display
    CHANGING
      it_fieldcatalog = it_fcat_ekko
      it_outtab       = it_ekko.

  CALL METHOD ob_grid2->set_table_for_first_display
    CHANGING
      it_fieldcatalog = it_fcat_ekpo
      it_outtab       = it_ekpo.

In the PAI block we shall validate the BACK, EXIT and CANCEL button by user command. Here 2 custom containers and 2 grids must be freed and internal tables must be refreshed. Then we shall leave to screen 0.

CODE:
  IF   sy-ucomm = 'BACK'
    OR sy-ucomm = 'EXIT'
    OR sy-ucomm = 'CANCEL'.

    FREE: ob_grid1, ob_grid2, ob_custom1, ob_custom2.
    REFRESH: it_ekko, it_ekpo.
    LEAVE TO SCREEN 0.
  ENDIF.

Hey Sandip ,
Nice work Simplified the whole approach .
I have 5 small screens to be displayed on one screen . Each screen(ALV grid) has to have one push button down .

Using this approach in OOPS how do i add the buttons for each alv ?
i suppose each button should be linked to that particular container ?
Can you let me know how do i call this buttons from each container ?

Thanks
Faran
