Rachel --
I cannot reproduce your error message, so I'm wondering what's going on with
your system. Beyond this, however, why are you adding this custom field to
the Gantt Chart view? To make this field visible to all of your project
managers, you need to do the following:
1. Click Tools - Enterprise Options - Open Enterprise Global.
The Enterprise Global is your organization's "library" of custom enterprise
Views, Tables, Filters, Groups, etc. You must open it for editing to create
custom enterprise Views, Tables, Filters, and Groups.
2. Apply the Enterprise Gantt Chart view, if not already applied. The
Gantt Chart view should NOT be selected in the Enterprise Global file!
3. Add the new column to the Enterprise Entry table.
I suspect that you have probably already "polluted" your Enterprise Global
file with non-enterprise Views such as the Gantt Chart view, so you will
probably need to do the following additional steps while you have the
Enterprise Global file open:
1. Click Tools - Organizer.
2. In the list of Views on the RIGHT (in the Enterprise Global file),
select and delete any local Views such as the Gantt Chart, Resource Sheet,
etc. You should only see ENTERPRISE Views in the list, such as the
Enterprise Gantt Chart, plus any custom enterprise Views you have created.
3. Click the Tables tab.
4. In the list of Tables on the RIGHT (in the Enterprise Global file),
select and delete any local Tables such as the Entry table. You should only
see ENTERPRISE Tables in the list, such as the Enterprise Entry table, plus
any custom enterprise Tables you have created.
5. On the Tables tab, select the Resource option at the top.
6. Select and delete any local resource Tables, such as the Entry table.
7. Click the Close button.
When finished with both of the above operations, save and close the
Enterprise Global file, then exit and relaunch Project Professional 2007.
Let us know if this helps.
