I think you are not placing your code in PBO, do you? You need that to show your alv once the screen/selection screen is being prepared for display. Only then it will work. So you need the logic

MODULE pbo OUTPUT.
   check alv_container is initial.
    "create container
    ...
    "create ALV
     ...
    "dispaly ALV
ENDMODULE.

For selection screen of course you need to use AT SELECTION-SCREEN OUTPUT instead.

You check Tcode: DWDM where same codes of control frame work are available.

You have to create a screen and write the code for showing alv in PBO.

Hi all,

Thanks for you replies. I am trying to display ALV in a report. Once the user enters the value in the selection screen and execute it should display the ALV.

When i try to display the ALV using REUSE_ALV_GRID_DISPLAY it is working fine.

Since i am learning to create it using OO concept i wanted to bring that using OO.

Since it is a report program, no screens or modules are involved.

Thanks,

sri

Hello Arunsri,

If you are using OO method to display alv then you need to define screen in screen painter which will have custom container control on it.

Once you are done with selection of data into internal table then you need to call that screen using

CALL SCREEN <scr_number>.

This will trigger PBO module of screen where you need to check if instance for grid and container are already created or not.

If not then you need to create then,

So, instead of cl_gui_docking_container you need to use cl_gui_custom_container and you need to pass name which is defined for the custom container in screen painter. Once custom container is ready pass this as container pass this to create alv_grid and the data table and it will display screen with the alv grid.

Hope this resolves you issue.

For more details please refer to SAP help for [ ALV using OO | http://help.sap.com/saphelp_47x200/helpdata/en/52/5f0607e02d11d2b47d006094192fe3/frameset.htm ]

You must create a screen for OOPS ALV. Just create a screen and call it in START-OF-SELECTION. As you are using docking container, no need to create a custom container in the screen. In PBO, you can write the code for ALV display.
