How to call a function in (CALL FUNCTION ..) in background - syntax

Former Member — Wed, 21 Apr 2010 04:35:37 GMT

Hi - ,

Can we call a function in background. If so, what is the syntax for it.

I need to call a function in backgorund with return parameter as timeout variable & do further processing.

Any updates will be highly helpful.

Thanks,

Gyanaraj

Hi,

You may create a separate report program and call your function module in that report normally.

Then call this report program in your program by submitting it as a background job.

You may use the following code in your report to submit the new report rpt_call_func(containing the function module)

DATA: global_job        LIKE tbtcjob.
  DATA: global_start_date LIKE tbtcstrt.
  DATA: global_step_tbl   LIKE tbtcstep OCCURS 0 WITH HEADER LINE.

  DATA: ls_jobs_of_step TYPE ty_bpxminfo.

  global_job-jobname        = 'MYJOBFOR_CALL_FUNC'.
  global_job-jobclass       = 'B'.
  global_job-newflag        = 'O'.
  global_step_tbl-program   = 'RSBTCPT3'.    "dummy step
  global_step_tbl-typ       = 'A'.
  global_step_tbl-status    = 'P'.     "scheduled
  global_step_tbl-authcknam = sy-uname.
  APPEND global_step_tbl.

  CALL FUNCTION 'BP_JOB_CREATE'
       EXPORTING
            job_cr_dialog   = 'N'
            job_cr_head_inp = global_job
       IMPORTING
            job_cr_head_out = global_job
            job_cr_stdt_out = global_start_date
       TABLES
            job_cr_steplist = global_step_tbl.

  SUBMIT rpt_call_func AND RETURN
          USER sy-uname
          VIA JOB global_job-jobname NUMBER global_job-jobcount
          WITH p_func_param1 = gv_var1
          WITH p_func_param2 = gv_var2
          WITH p_func_param3 = gv_var3
          WITH p_func_param4 = gv_var4.


  
  CALL FUNCTION 'JOB_CLOSE'
       EXPORTING
            jobcount             = global_job-jobcount
            jobname              = global_job-jobname
            strtimmed            = 'X'
       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.

Hi,

If your function module is RFC enabled, you can call the function module in background by using IN BACKGROUND TASK as follows:

CALL FUNCTION <function module name> IN BACKGROUND TASK [DESTINATION]

EXPORTING....

EMPORTING....

TABLES.....

EXCEPTIONS....
