Hi Sarita,

You can use the event DATA_CHANGED to check the value entered for a particular cell.

And in the same event you can update the value too.

METHODS handle_data_changed " DATA_CHANGED

FOR EVENT data_changed OF cl_gui_alv_grid

IMPORTING

er_data_changed

e_onf4

e_onf4_before

e_onf4_after

e_ucomm.

* ENTER key is pressed or

CALL METHOD go_grid->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_enter.

In this event you will get 2 methods in er_data_changed

One er_data_changed->GET_CELL_VALUE to read the value of a cell

Second er_data_changed->MODIFY_CELL to change the value of cell.

Regards,

Hi Sarita,

Below are the steps to achieve this functionality.

1. Register the event:

*--for tab

CALL METHOD go_alv->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_modified.

*-- for enter

CALL METHOD go_alv->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_enter.

2. Get the changed row,with this below code your changed data row will be selected :

CALL METHOD go_alv->check_changed_data.

3. Handle the event:

SET HANDLER go_respond_events->handle_data_changed_finish FOR go_alv.

4. You have to create the class for this before. In this class you have to update that value:

CLASS respond_events DEFINITION FINAL .

PUBLIC SECTION .

METHODS: handle_data_changed_finish FOR EVENT data_changed_finished

OF cl_gui_alv_grid.

ENDCLASS . "respond_events definition

CLASS respond_events IMPLEMENTATION .

METHOD handle_data_changed_finish.

LOOP AT <your intarnal tablewhich used for display> INTO <ls_>.

**just update the corresponding field of the field symbol here table will be updated

ENDLOOP.

ENDMETHOD. "handle_data_changed

ENDCLASS . "respond_events implementation
