Were you the one who posted this question yesterday? If not, it's very
coincidental!! Dale Howard answered this question in a previous thread. His
answer is:
A Global.mpt file resides on each Microsoft Project user's PC, and contains
the default "library" of project objects, such as Views, Tables, Filters,
Groups, Reports, etc. Each time the user opens Microsoft Project, their
Global.mpt file is opened in the background, which makes these project
objects available to the user. When the user applies a View, such as the
Tracking Gantt view, it is copied from the Global.mpt file into the active
project. When the user creates a custom project object, such as a custom
View, the new custom object can be copied via the Organizer (Tools -
Organizer) to the user's Global.mpt file for use with all present and future
projects that they manage.
The Enterprise Global file resides on the server containing the Project
Server database, and contains all of your company's custom project objects,
such as enterprise Views, Tables, Filters, Groups, Reports, etc. Each time
a user logs into Project Sever through Microsoft Project 2002 Professional,
both their personal Global.mpt file AND the Enterprise Global file are
loaded into memory, and are merged together to form a single file in the
background. If there is a personal project object (in the Global.mpt file)
and an enterprise project object (in the Enterprise Global file) that are
named the same, the user will be given the opportunity to rename their
personal object, because objects in the Enterprise Global always override
personal objects. The Enterprise Global is the way that new company project
objects can be rapidly deployed across the enterprise to all project
managers.
