Alternatively, you can switch your job to the Canceled statues.
This will remove the job from your schedule and reports and you will still have access to the information.
Deleting a job
Open any job by clicking the job id from your schedule or reports.
Scroll to the bottom of the Info tab and click the delete job button.

If you can not see the delete button, then your user is probably restricted from that option and you will need to ask you account Admin/ Owner for those permissions,
