SET_TABLE_FOR_FIRST_DISPLAY in I_CALLBACK_USER_COMMAND

[former_member307359]

Hi,

Can someone please help me with this one:

I'm doing an OOP with the use of CALL METHOD GRID1->SET_TABLE_FOR_FIRST_DISPLAY and I want to use similar functionality of 'REUSE_ALV_GRID_DISPLAY'->I_CALLBACK_USER_COMMAND. Since the CALL METHOD doesn't have I_call_back functionality. The alternative is to code it using classes, particularly SET_HANDLER.

Can someone please give me a working code for this? I'm still new with this type of class programming.

Thanks a lot.

Hi,

- Get the book "An Easy Reference for ALV Grid Control" chapter "Event Based Additional Functionalities "  the book is here

- Package SLIS demo programs.

- The wiki .

Hi,

Try like this ,

Declare screen, custom container, methods etc like,

first declare data :  IT_rec_Fcat TYPE lvc_T_fcat,

   WA_rec_Fcat TYPE lvc_s_fcat,

ob_custom TYPE REF TO cl_gui_custom_container ,

   ob_grid1  TYPE REF TO cl_gui_alv_grid .

CLASS lcl_event_receiver DEFINITION.

   PUBLIC SECTION.

   METHODs : handle_double_click FOR EVENT double_click OF cl_gui_alv_grid IMPORTING e_row e_column.

   ENDCLASS.

DATA : v_event_receiver TYPE REF TO lcl_event_receiver.

perform build_fcat.

   CALL SCREEN 9000 .

within that screen's OUTPUT part>

* This will create a container

    CREATE OBJECT ob_custom

       EXPORTING

         container_name = 'CONTAINER' .

CREATE OBJECT : v_event_receiver.

     SET HANDLER v_event_receiver->handle_double_click FOR Ob_grid1.

CALL METHOD ob_grid1->set_table_for_first_display

       EXPORTING

         i_structure_name = 'IT_REC_FCAT'

       CHANGING

         it_outtab = it_OUT_REC

           IT_FIELDCATALOG  = IT_REC_FCAT[]  .

>>

CLASS lcl_event_receiver IMPLEMENTATION.

     METHOD handle_double_click.

       READ TABLE it_out_rec INTO wa_out_rec INDEX e_row-index TRANSPORTING kunnr.

SUBMIT RFITEMAR with DD_KUNNR-LOW = wa_out_rec-kunnr

                       WITH X_AISEL = 'X'

                       with SO_BUDAT in s_budat

*                      WITH %%DYN011-LOW = '1300000032'

                       AND RETURN .

ENDMETHOD.

DO NOT forget to create other part & declaration.

Hope this code will help you.

Try like that.

Thanks.

Did you use search tool there are already some OO ALV samples at scn.

You'll need to have a local class+object to handle a EVENT the ALV Class will trigger.

Start with the ALV OO examples you can find in SCN, but don't just Copy+Paste. Try to understand what you're doing by learning about OO concepts.
