Heather,
While working with the people at my company, I've found
that the most common problem that cause these erroneous
allocations come from PM's who copy their files and keep
on going (this causes an essential duplication of resource
usage). Later, they will delete the old instance of the
project and have smooth way to retreat to a point where
they can remove the older resource allocations.
Nevertheless, I've found if you can determine the
project name where you want to remove them from, you can
somewhat easily do something about it. Specifically:
1. Determine the projects the resource are allocated
to. You can do this by adding the "Project" column
to the Resource Usage view of the resource pool.
2. Create create a new project plan in the same
location (!) and with the same name (ie, no tasks
in it)
3. Associate the new plan with the resourcce pool
where the error exist (Tools -> Resource Sharing ->
Share Resources; associating the blank project
with the resource pool.
4. Then, save and close the project. This should
remove all of the old task assignments associated
with the original (lost) plan.
5. In cases where there were multiple plans originally
stored in the same directory, you can get done
pretty quickly - simply rename the file to the next
one on the list, open it, save it, and close it.)
Good luck ... Earl
