Check In Plans Dialog Box
Use the Check In Plans dialog box to check in project plans manually. The dialog box displays all plans that are currently checked out to you and to others.
DPS automatically checks in plans when you switch from Planning mode to Project mode in the Projects hub, select a different project, log out of DPS, navigate to a different URL, use the browser's Refresh option, or close the browser. However, there may be situations in which you must use this option to manually check in plans.
You can check in any plans that are checked out to you. If your security role provides the necessary access, you can also check in plans that are checked out to other users.
