Problem in scheduling job in back ground

Question

hi all,
My project scenario is ,i have written a program to create WBS element.
For 1 WBS creation ,In production it takes 20 to 30 min to create as there are many transactional bdcs.
so i want to run that perticular code (all bdcs) in back ground.
so i wrote another program with name 'zback_job_for_wbs_creation' and added all the required code.
in old program,i have written some code to execute this new program in back ground . this code is below..
FORM submit_for_job.
  TABLES:btcevtjob.
  DATA:l_jobname LIKE tbtco-jobname,
       l_jobnumber LIKE rsjobinfo-jobnumb.
  DATA: count LIKE btcevtjob-jobcount,
        jobname LIKE btcevtjob-jobname.
  DATA: job_was_released LIKE btch0000-char1.
  jobname = 'WBS_CREATION'.
  EXPORT s_scrnum TO MEMORY ID 'W_SCRNUM'.
  EXPORT iscrh TO MEMORY ID 'W_ISCRH'.
  EXPORT iscrl1 TO MEMORY ID 'W_ISCRL1'.
  EXPORT iscrl2 TO MEMORY ID 'W_ISCRL2'.
  EXPORT iscrl2b TO MEMORY ID 'W_ISCRL2B'.
  EXPORT iscrl2a  TO MEMORY ID 'W_ISCRL2A'.
  EXPORT iscrl1a  TO MEMORY ID 'W_ISCRL1A'.
  CALL FUNCTION 'JOB_OPEN'
        EXPORTING
              jobname          = jobname
       IMPORTING
              jobcount         = count
  SUBMIT zback_job_for_wbs_creation
  with S_SCRNNUM IN S_SCRNUM
  and return via JOB JOBNAME NUMBER COUNT TO SAP-SPOOL
  WITHOUT SPOOL  DYNPRO.
  CALL FUNCTION 'JOB_CLOSE'
      EXPORTING
     jobcount                    = count
     jobname                     = jobname
      strtimmed                   = 'X'
    IMPORTING
         job_was_released            = job_was_released
   EXCEPTIONS
        cant_start_immediate        = 1
        invalid_startdate           = 2
        jobname_missing             = 3
        job_close_failed            = 4
        job_nosteps                 = 5
        job_notex                   = 6
        lock_failed                 = 7
        OTHERS                      = 8
here i have put break-point in my submitted program..but its not going to the program and job gets closed successfully without executing my code( Submitted Program).
in above submit statement , if i just write submit progname and return ,then it goes to program.
but job_close function module throws exception no 5.
so pls help me out for this..
i want my submitted program to be run in back ground..
thanks.

Hi,
Start Job Monitor SM37 and search for your job. I think you will find it.
Jobs are not linked to GUI frontend. So you can't debug your background job in that way.
If you want to debug you must be tricky.
Code a never ending loop with an exit condition which you can control by debugging.
DATA:
stop_for_capture.
DO.
IF sy-uname NE 'HABICH'. "change to your account
EXIT.
ENDIF.
IF NOT stop_for_capture IS INITIAL.
EXIT.
ENDIF.
ENDDO.
When your job is running, start TA SM50 and mark relevant batch work process and
choose by menu program -> program -> debugging.
