Options
Schedule list
Lists the schedules for this job.
New
Create a new schedule. After you create the schedule, the schedule is added to the job.
Pick
Select a schedule from the existing schedules. Because a job and schedule must have the same owner, this option will only allow you to pick from schedules that you own.
Edit
Edit the selected schedule to change job schedule properties.
Remove
Remove the selected schedule from the job. If no other jobs use the schedule, the schedule is deleted from the database.
