Hi Ateeq,
Define your internal table as similar to that of the database table. Have another internal table that has the key fields of the database table and two additional fields, one for line number and another for page number.
So the tables are as follows
DATA: BEGIN OF db_itab OCCURS 0.
INCLUDE STRUTURE <your db table name here>.
DATA: END OF db_itab.
DATA: BEGIN OF itab_out OCCURS 0,
key1 LIKE <your db table key field 1>
key2 LIKE <your db table key field 2>
.... as many fields as the key fields of your db tab
linno like sy-linno,
pagno like sy-pagno.
DATA: END OF itab_out.
Now when you are writing the output, you will fill the itab_out as follows.
LOOP AT db_itab.
WRITE:/ v_check as checkbox,
db_itab-key1,
db_itab-key2,
..... whatever db_itab-field
MOVE-CORRESPONDING db_itab to itab_out.
MOVE: sy-linno TO itab_out-linno,
sy-pagno TO itab_out-pagno.
APPEND itab_out.
ENDLOOP.
Now after the button modify is pressed, you will need to do the following
LOOP AT db_itab.
CLEAR itab_out.
READ TABLE itab_out WITH KEY key1= db_itab-key1
key2 = db_itab-key2.
CHECK sy-subrc = 0.
READ LINE itab_out-linno OF PAGE itab_out-pagno.
CHECK sy-subrc = 0.
IF sy-lisel+0(1) <> 'X'.
*-- box not checked
DELETE db_itab.
ENDIF.
*--your position where you wrote the checkbox, in my
* case I wrote it at 1st position. So my offset will be
* 0(1).
ENDLOOP.
After this loop you will have only the records that the user checked for modification. So use the following statement to update the database table now.
MODIFY <your db table> FROM TABLE db_itab.
If this helps, please close the post.
