The final step in the review process is to close the Plan Review project. Once a project is closed, that project's information can no longer be modified by the submitter. This includes all project documents, project locations, assigned users, and configured user roles.
Note:
The only information that can be modified after a project has been closed are the review comments. See Adding Documents to a Project for information on creating and modifying comments.
To close a project, select the project and click the Close button from the ribbon.
