Hi Gopi,
The only change that you have to do is vary the PACKAGE SIZE according to your need. Instead of 300,000 which is set right now, give the PACKAGE SIZE as 1,000,000. But that all depends upon your requirement.
Now, I think your limit is 350,000. If that is the case, then give PACKAGE SIZE 350,000 and instead of writing open dataset outside SELECT, put in before ENDSELECT.
i.e.
DATA : it_bseg    TYPE TABLE OF bseg,
       v_size     TYPE i VALUE '350000',
       v_filename TYPE string VALUE give application server path + file name.
SELECT *
  FROM bseg
  INTO TABLE it_bseg PACKAGE SIZE v_size
  WHERE condition.
IF it_bseg[] IS NOT INITIAL.
  OPEN DATASET v_filename FOR APPENDING IN TEXT MODE ENCODING DEFAULT.
  SORT IT_BSEG BY BELNR.
  LOOP AT it_bseg INTO x_bseg
    TRANSFER x_bseg TO  v_filename.
  ENDLOOP.
  CLOSE DATASET v_filename.
ENDIF.
ENDSELECT.
Reward points if the answer is helpful.
