Hello Kiran,

Did you see the help for open dataset statement ?

You can try this :

OPEN ... FOR APPENDING opens the file in append mode.

Hi kiran,

I use OPEN DATASET multiple times a day to write to a file sequentially. This does not delete the previous record. It only adds to the file.


DATA: dsn(40) VALUE '/usr/filename.txt'.
DATA: wa_itab like line of itab.

OPEN DATASET dsn FOR APPENDING IN TEXT MODE ENCODING DEFAULT.
IF SY-SUBRC = 0.
LOOP AT ITAB INTO wa_itab.
TRANSFER wa_itab TO dsn.
ENDLOOP.
ENDIF.
CLOSE DATASET dsn.

Let me know if you have any questions.
