Background Information
This problem occurs when the Project Server Administrator applies or copies the Gantt Chart view or any other non-enterprise view after checking out the Enterprise Global for editing. By doing this, the Gantt Chart view and the Entry table are copied into the Enterprise Global. Because the Gantt Chart view and Entry table are local objects that are found in each user's Global.mpt file, they should not appear in the Enterprise Global because it is reserved only for enterprise objects. Once local objects such as the Gantt Chart view are accidentally copied into the Enterprise Global, they will cause error messages every time a project manager opens a project from Project Server.
Warning: The Project Server administrator must be careful when checking out the Enterprise Global to make sure that only enterprise objects are present in the Enterprise Global, including Views, Tables, Filters, Groups, Reports, etc.

The Project Server administrator must perform the following steps to resolve this issue:
1. Open Microsoft Project Professional and log into Project Server with administrator permissions

7. From the list of Tables on the right (in the Enterprise Global), select the Entry table and any other non-enterprise tables (do not select the Enterprise Entry table)
8. Click the Delete button
9. Click the Close button
10. Save and close the Enterprise Global file
11. Close Microsoft Project
12. Ask all Project Managers to exit Microsoft Project Professional and to log into Project Server again to get the latest changes to the Enterprise Global
