Dave --
I believe that your problem is being caused by two situations in your
environment:
1. Your project managers are using local resources in their project plans
when they should be using Generic resources instead.
2. You have automatic account creation enabled in Project Web Access.
To eliminate this problem in the future, you should do several things:
1. Add as many Generic resources to the Enterprise Resource Pool as are
needed to meet your project managers' assignment planning needs. When you
are creating Generic resources, make sure that you double-click the
resource's name, and then select the Generic checkbox in the Resource
Information dialog box. Doing so will formally designate the resource as
Generic. Once you have done this, ask your project managers to replace all
of their local resources with the Generic resources from the pool. After
each PM replaces their local resources, he/she should click Collaborate -
Publish - All Information to make sure the latest information about the
project and its assignments are published to PWA.
2. In the future, project managers should only use local resources to
account for the work of outside workers, such as consultants, contractors,
etc. When your PM's are doing draft planning, they should use Generic
resources as "placeholders" until the human resources are actually known for
the project.
3. Disable automatic account creation in PWA. To do this, log into PWA
with administrator permissions. Click the Admin menu, then click the Manage
Organization link. In the Account Creation section, set all of the values
to Deny and then click the Save Changes button.
4. Once you have changed the automatic account creation settings, and all
of your PM's have replaced their local resources with Generic resources, and
published their plans to PWA, you can delete the unneeded PWA accounts for
local resources by merging them with a dummy user account. Hope these ideas
help.
