FM call in background task

Question

Hi,
I have called a function module in background task. Inside this FM I create application log and put in all the messages in the log which can be viewed using the transaction SLG1. But if the creation of the log fails I want to display the info to the user and exit the FM. I cannot display the info using the Message statement here. I tried to raise an exception, etc. from this FM so that I can process the exception in the calling FM and display a message. But this does not work as the execution of the calling FM and called FM in rfc proceeds simultaneosly. I know I can see the error using transaction sm58 but I am looking for an option wherein I can directly inform the user. Does someone have a suggestion how can proceed with this?
Thanks.
Best Regards,
Pooja

Hi
There are two ways for you to handle,
one manually setting up the job through SM36 which is better and convinient,
secondly through program using FM's JOB_OPEN, SUBMIT, JOB_CLOSE.
Find below steps in doing both:
Procedure 1:
1. Goto Trans -> SM36
2. Define a job with the program and variant if any
3. Click on start condition in application tool bar
4. In the pop-up window, click on Date/Time
5. Below you can see a check box "Periodic Job"
6. Next click on Period Values
7. Select "Other Period"
8. Now give '15' for Minutes
9. Save the job
In SM37 u can check the status of the jobs that u have assigned to background...
Here u mention the job name or the report name to check the status of the job...
After mentioning the job name or program name u just execute it.. ( without any name also u can execute then it gives u all the jobs set by your user name..
the status colud be released,active,finished etc..
Procedure 2 via Program:
Below is a sample code for the same. Note the ZTEMP2 is the program i am scheduling with 15mins frequency.
DATA: P_JOBCNT LIKE TBTCJOB-JOBCOUNT,
      L_RELEASE(1) TYPE c.
   CALL FUNCTION 'JOB_OPEN'
     EXPORTING
       JOBNAME                = 'ZTEMP2'
    IMPORTING
      JOBCOUNT               = P_JOBCNT
    EXCEPTIONS
      CANT_CREATE_JOB        = 1
      INVALID_JOB_DATA       = 2
      JOBNAME_MISSING        = 3
      OTHERS                 = 4.
   IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
   ENDIF.
   SUBMIT ZTEMP2 VIA JOB 'ZTEMP2' NUMBER P_JOBCNT
          TO SAP-SPOOL WITHOUT SPOOL DYNPRO
          WITH DESTINATION = 'HPMISPRT'
          WITH IMMEDIATELY = SPACE
          WITH KEEP_IN_SPOOL = 'X' AND RETURN.
   CALL FUNCTION 'JOB_CLOSE'
     EXPORTING
       JOBCOUNT                          = P_JOBCNT
       JOBNAME                           = 'ZTEMP2'
       STRTIMMED                         = 'X'
       PRDMINS                          = 15
    IMPORTING
      JOB_WAS_RELEASED                  = L_RELEASE
    EXCEPTIONS
      CANT_START_IMMEDIATE              = 1
      INVALID_STARTDATE                 = 2
      JOBNAME_MISSING                   = 3
      JOB_CLOSE_FAILED                  = 4
      JOB_NOSTEPS                       = 5
      JOB_NOTEX                         = 6
      LOCK_FAILED                       = 7
      INVALID_TARGET                    = 8
      OTHERS                            = 9.
   IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
   ENDIF.
Hope the above helps you.
Alternately use CALL FUNCTION func IN BACKGROUND TASK
