As the project server administrator, you have the authority to define customizations needed by your organization and then propagate those customizations to all enterprise projects as the accepted project management standards.
To create and disseminate custom project elements, you use the enterprise global template, also simply known as the enterprise global. You check out the enterprise global and then customize any number of Microsoft Project elements as necessary. You can define views, tables, filters, toolbars, macros, custom fields, and more. When you check in the enterprise global with your changes, your changed elements become part of all projects throughout the enterprise.
