Resourse units keep changing - MSP2003

[Bryan]

I've a task with multiple resourses. One of them shows 200% in units. I try
to change to 100% and it changes it back. I can't seem to change anything
that will allow me to change that. Help?

On that same note, how can I tell project to NEVER use anything but 100%.
These are all people and can only be <= 100%.

There are several ways that Microsoft Project will adjust the Units on a
task assignment. Here's a couple of scenarios:

I assign Mickey Cobb at 50% Units and 40 hours of Work to a 10-day Fixed
Duration task. Microsoft Project schedules her at 4 hours of Work per day
over the life of the task. During the first week she reports only 2 hours
of Actual Work each day, or 10 hours of Actual Work for the week. Because
of this, Microsoft Project will reschedule the 30 hours of Remaining Work
into the second week at 6 hours per day. The Units value will be
recaluclated at 75%. Why? The Units value that you see on the task
assignment is actually the Peak Units value, which represents the largest
Unit commitment during any time period on the task. Because she is
scheduled to work 6 hours per day in the second week, the Units value
(actually Peak Units) is now 75% (6 hours is 75% of an 8-hour day).

I assign Mickey Cobb at 100% Units and 40 hours of Work on a Fixed Units
task. Microsoft Project schedules her at 8 hours of Work per day over the 5
days of the task. During the week, Mickey enters the following hours in her
timesheet:

M T W Th F
8 12 12 8

Mickey finished the task one day early, but worked long days on Tuesday and
Wednesday. Because she worked 12 hours in each of those time periods, her
Units value (remember it's actually Peak Units) is recalculated at 150% (12
hours is 150% of an 8-hour day). That's how the software works and there is
no way to tell the software not to do it. If you see 200% Units on a task
assignment, the software is telling you to investigate and see what's
happening. Hope this helps.

Actually people can be more than 100%. If I have 5 people on the custodial
staff and their skills are essentially interchangeable, I can show them in
my resource list as a single entry with a max allocation of 500%. If it's
assigned to a task at 200% that means I have two custodians working together
on the task. That's why you can't tell project to never exceed 100%.

As to why your assignment seems to be locked in and MSP won't let you change
the 200% to 100% that's a bit of a puzzle. Have you posted any actual
progress to the task?
