SQL Enterprise Job Manager provides you with an option to schedule a projection period for all your instances, jobs, tasks, and job chains across your environment.
To access this option, go to the Administration tab, and click Set Projection Period under the Schedule section. Once you click on it, SQL Enterprise Job Manager opens a new window with this option. You can specify the number of days for what you want to set the projection period by using the buttons on the corner of the box or typing the number, then click Apply to save your changes.
