To delete a single job, select it in the Automation -> Jobs folder of the Object Explorer and choose Delete from the shortcut menu.
To delete multiple jobs, select the Automation -> Jobs folder and choose Properties from the shortcut menu to open the job list in the Properties panel. Select multiple jobs in the grid using CTRL+Click or SHIFT+Click operations and choose delete from the shortcut menu in the grid to delete all selected jobs. When the job is deleted, it also deletes it from all monitors that use this job as a response to alert events. You will be prompted to confirm the job deletion if there are monitors that use this job.
