Hi,
Use event data_changed.
When 'SAVE' is pressed, call check_changed_data( ) which will trigger event data_changed.
Inside handler method copy the modified cells to table.
*PAI
When 'SAVE'.
g_o_grid->check_changed_data( ).  " It triggers event 'data_changed'.
LOOP AT g_t_modcells INTO g_r_modcells.   " Loop at modified cells table
READ TABLE git_data INTO gwa_data INDEX g_r_modcells-row_id .      " <---- Ur code
ENDLOOP.
clear: g_t_modcells[],g_t_modcell[].
*Declare data for handler method.
Data:  g_t_modcells type lvc_t_modi,
          g_t_modcell type lvc_t_modi.
*Declare handler method for event 'data_changed'.
METHODS: data_changed FOR EVENT data_changed OF cl_gui_alv_grid IMPORTING er_data_changed.
*Handler method implementation
  METHOD data_changed.
    IF er_data_changed->mt_good_cells[] IS NOT INITIAL.
      g_t_modcell[] = er_data_changed->mt_good_cells[].
      APPEND LINES OF g_t_modcell TO g_t_modcells.  " Modified cells are copied to table g_t_modcells[]
    ENDIF.
  ENDMETHOD.
Thanks,
