Check-in enterprise projects (Project Server 2010)
You can force the check-in of an enterprise project that is checked out. Note that forcing a check-in of a project that is being modified by a user may result in the loss of those changes. We highly recommend that users check in projects in the typical manner and that you use force check-in only when it is absolutely necessary.
Use the following procedure to check in enterprise projects.

On the Server Settings page, click Force Check-in Enterprise Objects.
From the Select the type of object you want to force check-in drop-down list, select Enterprise Projects.
