Hi, 
   If you are doing it with oops concept then here are the steps for that.
1) Declare DATA : er_data_changed TYPE REF TO cl_alv_changed_data_protocol,
       data_changed TYPE REF TO cl_alv_changed_data_protocol.
--For getting the row no of of the row which is edited by user
DATA : ls_mod_cell TYPE table of lvc_s_modi with header line,
lv_value TYPE lvc_value .
in your program
2) Define a class
CLASS notification DEFINITION.
  PUBLIC SECTION.
    CLASS-METHODS : handle_data_changed FOR EVENT data_changed OF cl_gui_alv_grid IMPORTING er_data_changed.
ENDCLASS.                    "NOTIFICATION DEFINITION
3) For that class write the implementation
CLASS notification IMPLEMENTATION.
  METHOD handle_data_changed.
    PERFORM handle_data_changed USING er_data_changed.
  ENDMETHOD.                    "handle_data_changed
ENDCLASS.                    "NOTIFICATION IMPLEMENTATION
4) In the  PERFORM handle_data_changed  you code like this
FORM handle_data_changed  USING er_data_changed type ref TO
cl_alv_changed_data_protocol.
SORT er_data_changed->mt_mod_cells BY row_id .
LOOP AT er_data_changed->mt_mod_cells
INTO ls_mod_cell .
append ls_mod_cell.
ENDLOOP.
*LS_MOD_CELL will have all the rows which were edited
and all the updated data corresponding to those rows*
You can now use the the data which is in LS_MOD_CELL
to update into your DB Table.
LOOP at ls_mod_cell.
  READ TABLE itab3 INTO t_output INDEX ls_mod_cell-row_id.
ENDLOOP.
ENDFORM.                    " handle_data_changed
