ALV data change event handling

[Former Member]

Hi,

I have 2 alv grid's present in the same screen. These tables are of different structures having a field in common. This field has an F4 help(fixed values defined at field level). So, when i am making changes to this field in any of the two tables, in the datachange handler i am unable to differentiate the table name in which the change has been done.

I am using cl_alv_grid_display for alv.

Kindly help me out in figuring out the exact table in which the changes took place.

Thanks in advance,

Hi Poorvika,

You need to define 2 separate event handler methods for your case

and assign one method to each of your ALV grids

as the event DATA_CHANGED does not help in identifying which ALV trigerred the event.

define a class , 2 objects to catch this event.

CLASS alv_event_handler DEFINITION DEFERRED.

DATA: ref_handler_alv1 TYPE REF TO alv_event_handler,

ref_handler_alv2 TYPE REF TO alv_event_handler.

CLASS alv_event_handler DEFINITION .

PUBLIC SECTION .

METHODS:

*DATA_CHANGED

handle_DATA_CHANGED FOR EVENT DATA_CHANGED OF cl_gui_alv_grid.

ENDCLASS.

CLASS alv_event_handler IMPLEMENTATION.

• DATA CHANGE

METHOD handle_DATA_CHANGED.

ENDMETHOD. "handle_double_click

ENDCLASS.

• two objects to catch two events of these two alv.

SET HANDLER ref_handler_alv1->DATA_CHANGED FOR ref_grid1.

SET HANDLER ref_handler_alv2->DATA_CHANGED FOR ref_grid2.

Hi,

What you can do is create different instance for both the grid and use like:-

* to reflect the data changed into internal table
      DATA : ref_grid TYPE REF TO cl_gui_alv_grid. "new

      IF ref_grid IS INITIAL.
        CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
          IMPORTING
            e_grid = ref_grid.
      ENDIF.

      IF NOT ref_grid IS INITIAL.
        CALL METHOD ref_grid->check_changed_data.
      ENDIF.

Hope this helps you.
