SET_TABLE_FOR_FIRST_DISPLAY in I_CALLBACK_USER_COMMAND

former_member307359 — Fri, 06 Jun 2014 13:30:47 GMT

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 .

Regards.

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.
