        data(132) TYPE c,
END OF reportlines.
DATA: first_line TYPE i,
      last_line  TYPE i.
DATA: v_syspono LIKE tsp01-rqident.
DATA mi_rq2name LIKE tsp01-rq2name.
DATA f_repid LIKE sy-repid.
DATA v_rqident LIKE tsp01-rqident.
START-OF-SELECTION.
  DO 120 TIMES.
    write: / sy-index,
             'Hello'.
  ENDDO.
TOP-OF-PAGE.
  f_repid = 'ZMAIL7'.
  CONCATENATE f_repid0(9)'_' sy-uname0(3) INTO mi_rq2name.
  SELECT * FROM tsp01
           INTO tsp01
           WHERE rq2name = mi_rq2name
           ORDER BY rqcretime DESCENDING.
    v_rqident = tsp01-rqident.
    EXIT.
  ENDSELECT.
  IF sy-subrc NE 0.
    CLEAR v_rqident.

WAIT UP TO 50 SECONDS.
    v_syspono = v_rqident.
  v_syspono = sy-spono.

Hi
now i'm using only this fn module
CALL FUNCTION 'RSPO_RETURN_SPOOLJOB'
  EXPORTING
    rqident = V_rqident
  first_line = startline
  last_line = endline
   desired_type = 'RAW'
  IMPORTING
    real_type = real_type
  TABLES
  buffer = LT_TEXT
EXCEPTIONS
  no_such_job = 1
  job_contains_no_data = 2
  selection_empty = 3
  no_permission = 4
  can_not_access = 5
  read_error = 6
  type_no_match = 7
  OTHERS = 8.
IF sy-subrc <> 0.
  EXIT.
ENDIF.
i'm getting mail correly if it is online/foreground.
if it is background only first page i'm getting
.spool is having the correct/all data.
if in foreground i hardcoded the spool no to the above fn mdoule it is working fine.
i feel there is some restriction in background
just now i searched in net. i saw some below msg
If you run a report in the background that has more than 255 characters in the output, the spool cuts the output to 255 characters. An OSS Note has been applied to the system which created a new output format that allows for up to 380 characters of output in the spool. When you rerun the report, the TOP-OF-PAGE contents all get outputted in complete, but the data for the report (all WRITE statements after TOP-OF-PAGE) gets cut off at 255 characters. It works fine for an ALV report but it doesn't work for a regular WRITE statement report.
