TO ADD DATA IN YTABLE

Question

I am doing a dialog program. I have created a screen 1002 which has a table control.
I first created a ytable. In the report i created an itab which includes structure of this ytable. Then in the screen painter i created a table control which includes this itab. It contains all the fields of this itab. In screen flow logic i wrote:
In PBO :
LOOP AT ITAB WITH CONTROL TBCL CURSOR TBCL-CURRENT_LINE.
endloop.
In PAI:
LOOP AT ITAB.
ENDLOOP.
In the report i wrote:
CONTROLS: tbcl TYPE TABLEVIEW USING SCREEN 1002.
START-OF-SELECTION.
CALL SCREEN 1002.
Now when i run the report , I see the table control.
Now i want to add data in this table field so that it gets added in the ytable created. When i click the save button on the same screen it should get saved in the ytable. Now how should i proceed.

hi priti.....
use the following coding:
In PBO :
LOOP AT ITAB into wa WITH CONTROL TBCL CURSOR TBCL-CURRENT_LINE.
endloop.
In PAI:
LOOP AT ITAB.
module hold_data.
ENDLOOP.
inside the module:
    modify table itab from wa index tbcl-current_line.
    if sy-subrc eq 4.
     append wa to itab.
   endif.
<b>what happens here is this:</b>
each and every time you enter a value in your TC and press enter, the following things  take place:
  First use a workarea for your itab. i have given it as wa.
   the loop for the itab begins in the PAI.
  for each and every loop the first record in your TC will be brought into the wa and compared with the itab value.
if the values are same(sy-ssubrc = 0 ), there will be no change.
if not so the value in the wa will be appended in you itab as well as TC.
now all the values will be stored in your itab. then you can use the normal method to save the values from itab to ytable
