Save Data From Grid to Database

Question

Hello All,
I want to create a form to save data from a grid to the database just like the SAP Forecast Form .
My requirements are as follows :-
I have created a Table  in which there are three fields ItemCode,Date,Qty
But while entering user will first select the Date ranges (from - To) and based on that date range
no. of columns will be created as it will be dynamic and then user will enter the corresponding quantity for that item and date
just like the Sales Forecast (SAP) Form .
Form will be like :-
From Date - 10/10/11  ToDate - 13/10/11
Row Levels Fields :-
ItemCode    10/10/11  11/10/11  12/10/11  13/10/11
A0001           100           150          200            300
While updating system will put the  data in database table as :-
ItemCode        Date             Quantity
A0001            10/10/11          100
A0001             11/10/11          150
A0001             12/10/11          200
A0001              13/10/11          300
This is what i want to do .
Please suggest how to proceed with this using a Matrix or a grid.
Thanks & Regards,
Amit

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
