Dynamic creation of variant

Question

Hi Friends,
      I need to schedule a report in background at runtime.... for that i got a function Module SUBST_SCHEDULE_GENERATOR
in this function module, we need to pass variant, but as the report is a BDC and should run for different values at every run, values i can get at runtime.Here i need to create a variant for those values ........so that i can pass it to the FM.
Is there any function module or any other way to create a variant at runtime.
or is there any other way to create a background job snd in that  case how to pass screen fields..
Thanks & Best regards
Dev

Try SUBMIT statement. Check code below.
(Ref: SAP documenation.
Sample:
DATA: number TYPE tbtcjob-jobcount,
      name TYPE tbtcjob-jobname VALUE 'JOB_TEST',
      print_parameters TYPE pri_params.
CALL FUNCTION 'JOB_OPEN'
  EXPORTING
    jobname          = name
  IMPORTING
    jobcount         = number
  EXCEPTIONS
    cant_create_job  = 1
    invalid_job_data = 2
    jobname_missing  = 3
    OTHERS           = 4.
IF sy-subrc = 0.
  SUBMIT submitable TO SAP-SPOOL
                    SPOOL PARAMETERS print_parameters
                    WITHOUT SPOOL DYNPRO
                    VIA JOB name NUMBER number
                    AND RETURN.
  IF sy-subrc = 0.
    CALL FUNCTION 'JOB_CLOSE'
      EXPORTING
        jobcount             = number
        jobname              = name
        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.
    IF sy-subrc <> 0.
    ENDIF.
