Hello,

I think first you have to check some standard sap program :

BCALV_EDIT_01 Switch on and off the ready-for-input status of the entire grid

BCALV_EDIT_02 Define ready-for-input status at cell level

BCALV_EDIT_03 Verification of modified cells

BCALV_EDIT_04 Delete and append rows

BCALV_EDIT_05 Checkboxes

BCALV_EDIT_06 Dropdown Listbox at Column Level

BCALV_EDIT_07 Dropdown Listbox at Cell Level

BCALV_EDIT_08 Integrate Non-Standard F4 Help

there simple process like you have to add a container on a screen

and in report program

create an instance


data  g_container TYPE scrfname VALUE 'ZGW_CONTAINER',
      grid1  TYPE REF TO cl_gui_alv_grid.

where zgw_container is conatiner name which is asing to screen

then call the method set_table_for_first_display of class cl_gui_alv_grid .

pass the require parameter to that method.


    CALL METHOD GRID1->SET_TABLE_FOR_FIRST_DISPLAY
      EXPORTING
*    I_BUFFER_ACTIVE               =

Create a Dynpro using SE51, in the dynpro (layout) create a "Custom Control".

In your Abap (or in PBO) create a container object ([cl_gui_custom_container|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=cl_gui_custom_container&adv=false&sortby=cm_rnd_rankvalue]) with container_name equal to the name of your Custom control then create an alv grid object ([cl_gui_alv_grid|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=cl_gui_alv_grid&adv=false&sortby=cm_rnd_rankvalue]), then use the method set_table_for_first_display on your alv grid object.

Look at

- [ALV Grid Control (BC-SRV-ALE)|http://help.sap.com/printdocu/core/Print46c/en/data/pdf/BCSRVALV/BCSRVALV.pdf]

- [SAP Container|http://help.sap.com/printdocu/core/Print46c/en/data/pdf/BCCIDOCK/BCCIDOCK.pdf]

Also don't hesitate to use the SAP demos program, look at transactions

- DEMO_SCREEN_FLOW Demonstration for Screen Sequences

- DEMO_TRANSACTION Demonstration Transaction

- DWDM Development Workbench Demos

- SE83 Reuse Library

Hi Sia,

I think there is a new ABAP ALV Class .. which doesn't require a screen to be created for display.. check the package.

SALV_OBJECTS.

That's right, there is. The ALV Object model was introduced in NetWeaver 2004, which is an encapsulation of the existing ALV tools, the REUSE functions, and the CL_GUI_ALV_GRID class. The new Object model is OO based, and still allows to you show your grid in either full screen mode, which does not require you to create a screen, and it also provides container support, which allows to you embed the ALV control into your screens. Here is a document to get your started, and there are example programs which start withe SALV*

Hello

Please note that if you want to display your ALV list (CL_GUI_ALV_GRID) in fullscreen mode it is not required to have a custom container on the screen. Instead I usually use a docking container as parent for the grid control and simply LINK the docking container to the screen (see sample report ZUS_SDN_TWO_ALV_GRIDS in ).

Advantage of such a solution: you can easily re-link your docking container (including the control) to another screen if required.


* Link the docking container to the target dynpro
  CALL METHOD go_docking->link
    EXPORTING
      repid                       = syst-repid
      dynnr                       = '0100'
*      CONTAINER                   =
    EXCEPTIONS
      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.
 
 
* NOTE: dynpro does not contain any elements
  CALL SCREEN '0100'.
* Flow logic of dynpro (does not contain any dynpro elements):
*
*PROCESS BEFORE OUTPUT.
*  MODULE STATUS_0100.
**
*PROCESS AFTER INPUT.
*  MODULE USER_COMMAND_0100.
