You can set the project state to list and view the projects in certain states only.
For projects that are considered completed, you can set the state to Completed. Once the state is set to Completed, you cannot view elements or task elements in the project in Smart Review. You can only do certain actions, such as browsing the information of the elements, browsing the status of the tasks, and generating reports. You can set the project state back to Active in order to view elements or task elements in Smart Review.
