  Check Job Status:
  
  Go to transaction code SM37 in the SAP GUI.

  To cancel a job, select the job in SM37 and choose the option to cancel it.
  
  
  
  Re-schedule the Job:
  
  Once the conflicting job has been resolved (either completed or canceled), you can attempt to re-schedule the job that was previously failing.
