User exit EXIT_SAPLL03T_002 and jobs

Question

Hi everybody,
I have a problem with user exit EXIT_SAPLL03T_002 and trx LT12, i put code (the code is in the end) in the user exit in order to update the field QNAME from the standar table LTAP, the sentences for the update are in a job.
The problem is when a run the LT12, put the order and press enter the trx finish normally, but when i see the jobs resumen (SM37) there isnt any job.
Thank you for your help, see you.

Hi,
Check the print parameters. Probably after execution you may be deleting the job.
You can change the print parameters during runtime.
CALL FUNCTION 'GET_PRINT_PARAMETERS'
   EXPORTING
     no_dialog                    = 'X'
     user                         = sy-uname
   IMPORTING
  OUT_ARCHIVE_PARAMETERS       =
     out_parameters               = params
     valid                        = ws_valid.
  IF ws_valid <> space.   
    params-pdest = 'LOCL'.  "Destination
    params-primm = ''.      "Print Immediately
    params-prnew = 'X'.     "New Spool Request.
    params-armod = '1'.     "Print: Archiving Mode - Print Only
    params-linct = 65.      "Rows
    params-linsz = 255.     "Cols
    params-paart = 'X_65_255'.
    params-prrec = sy-uname.  "User name
    params-prsap = ''.      "Print: SAP Cover Page

endif.
  CALL FUNCTION 'JOB_CLOSE'
       EXPORTING
            jobcount             = ws_c_jobnum
            jobname              = ws_c_session
            strtimmed            = 'X'

            cant_start_immediate = 1

            job_notex            = 6

Also check the sy-subrc after JOB_OPEN.
