How to cancel the background job processing in ABAP programming?

Question

Hi,
I have a requirement where i need to cancel the job depending on some constraint. My code is something like this:
Select some data from the table.
if sy-subrc = 0.
Do nothing.
Else
Cancel the job
call function 'BP_JOB_ABORT'
  exporting
   jobcount                         = number
    jobname                          = name
EXCEPTIONS
   CHECKING_OF_JOB_HAS_FAILED       = 1
   JOB_ABORT_HAS_FAILED             = 2
   JOB_DOES_NOT_EXIST               = 3
   JOB_IS_NOT_ACTIVE                = 4
   NO_ABORT_PRIVILEGE_GIVEN         = 5
   OTHERS                           = 6
The above code is cancelling the job but it is throwing an exception called CX_SY_DYN_CALL_PARAM_MISSING because i dint pass job count. How can we find the job count of next job that is going to run? Or How to handle the exception which it is throwing. Even if i try to handle that exception something like this:
TRY
call function 'BP_JOB_ABORT'
  exporting
   jobcount                         = number
    jobname                          = name
EXCEPTIONS
   CHECKING_OF_JOB_HAS_FAILED       = 1
   JOB_ABORT_HAS_FAILED             = 2
   JOB_DOES_NOT_EXIST               = 3
   JOB_IS_NOT_ACTIVE                = 4
   NO_ABORT_PRIVILEGE_GIVEN         = 5
   OTHERS                           = 6
RAISE EXCEPTION TYPE CX_SY_DYN_CALL_PARAM_MISSING.
CATCH
CX_SY_DYN_CALL_PARAM_MISSING.
ENDTRY.
It avoids the exception but it doesnt cancel the job.  I even tried with function modules like JOB_OPEN
JOB_SUBMIT,BP_JOB_SELECT,BP_JOB_ABORT and tried to build some logic using status overview table (TBTCO) and TBTCP (Jobstep overview table).
Can someone suggest me the right way to write this program ?
Thanks in advance.

Hi,
Problem is solved.
Create an background job with 2 steps. The first step in the background job calls the program ZBACKJOB_STEP1.  In the variant we have a wrong material number
If the material number is not found in Mara, the next step in the job should not get executed and the job should get cancelled..
In the above posts i had asked how do I get the job count of the job that is currently triggering the program at the runtimeu2026..If u see the below code uu2019ll get to know.. We have to use the standard structure TBTCM which captures the properties/characteristics of the job.
REPORT ZBACKJOB_STEP1.
TABLES: MARA,TBTCM.
PARAMETERS : MATNR TYPE MATNR.
START-OF-SELECTION.
  SELECT SINGLE * FROM MARA WHERE MATNR = MATNR.
  IF SY-SUBRC IS INITIAL.
    WRITE / : 'This is the material selected on the selection-screen' , MARA-MATNR.
ELSE.
        CALL FUNCTION 'GET_JOB_RUNTIME_INFO'
      IMPORTING
        EVENTID                                    = TBTCM-EVENTID
        EVENTPARM                             = TBTCM-EVENTPARM
        EXTERNAL_PROGRAM_ACTIVE = TBTCM-XPGACTIVE
        JOBCOUNT                                = TBTCM-JOBCOUNT
        JOBNAME                                  = TBTCM-JOBNAME
        STEPCOUNT                              = TBTCM-STEPCOUNT
      EXCEPTIONS
        NO_RUNTIME_INFO                    = 1
        OTHERS                                     = 2.
    IF SY-SUBRC = 0.
      CALL FUNCTION 'BP_JOB_ABORT'
        EXPORTING
          JOBCOUNT                                     = TBTCM-JOBCOUNT
          JOBNAME                                       = TBTCM-JOBNAME
        EXCEPTIONS
          CHECKING_OF_JOB_HAS_FAILED  = 1
          JOB_ABORT_HAS_FAILED              = 2
          JOB_DOES_NOT_EXIST                   = 3
          JOB_IS_NOT_ACTIVE                      = 4
          NO_ABORT_PRIVILEGE_GIVEN       = 5
          OTHERS                                         = 6.
      IF SY-SUBRC <> 0.
      ENDIF.
    ENDIF.
  ENDIF.
