John --
Now that I understand your situation, I think you have a couple of options:
1. Assign these project managers to a milestone task that contains a
minimum amount of work. To do this, select any milestone in the project and
set its Duration at 1 hour. Then double-click the name of the milestone
task, select the Advanced tab, select the "Mark task as milestone" option,
and then click OK. Assign each of these project managers at 100% Units to
the task and publish the project.
2. Manually add each of these managers to the list of users for the
individual project's SharePoint subweb. To do this, log into PWA with
administrator permissions. Click Admin - Manage Windows SharePoint
Services - Manage SharePoint Sites. Select the site for the project in
question and then click the Go to Site Administration button. Click the
Manage Users link in the Administration section. Click the Add Users button
and manually add these project managers to the list of users for the site.
Be forewarned that if you ever synchronize the users for this site, you will
lose any users you added manually.
3. Change the permissions in the Project Managers group in PWA to give your
project managers Read-Only access to one another's projects. Log into PWA
with administrator permissions then click Admin - Manage users and groups.
Click the Group link in the sidepane, select the Project Managers group, and
then click the Modify Group button. In the Categories section, select the
My Organization category, and then set the Open Project permission to Allow
in the Permissions grid. Click the Save Changes button.
Just a couple of thoughts. Perhaps the others will have some ideas for you,
too.
