Validation of data in editable ALV report output for particular field

Question

Hi Experts,
I have one input enabled field in ALV output. How to validate the data once user enters  in that field and press enter? Is it possible to capture the value, hit the enter after user enters the data?
Thanks,
Surya Prakash

Halo Prakash,
1 First you should registeer the ENTER Event.
call method g_grid->register_edit_event
               exporting
                  i_event_id = cl_gui_alv_grid=>mc_evt_enter.
2 Declare event handler method for Event data_changed of cl_gui_alv_grid.
handle_data_changed
         for event data_changed of cl_gui_alv_grid
             importing er_data_changed.
3 Inside the Event handler method , you get the event parameter er_data_changed type ref to CL_ALV_CHANGED_DATA_PROTOCOL.
loop at er_data_changed->mt_good_cells into ls_good.
      case ls_good-fieldname.
        when 'FIELD1'.
          call method check_FIELD1.
        when 'FIELD2 '.
          call method check_FIELD2
      endcase.
    endloop.
4 Inside the Method check_FIELD1 and check_FIELD2 you can do the validation check .
call method er_data_changed->get_cell_value( Passing the row no and field name).
if the check  fails you can use add_protocol_entry to write the error.
5 Finally call
er_data_changed->display_protocol.
