I thought I had selected "fixed duration" under file; options. Received unusual constraints. Q: if i'm not going to be changing the unit allocations or resources as listed; is the change back all that important as I go through status updating through the tracking, variance, or baseline tables???

A bit more info would help. At a guess.. .MS Project, you've inserted rows midway into a project, and yes you need to change them all manually.

Is there a prize?

Will have to use the favourite phrase - it depends.

As Tim says, a bit more info would be useful, but it really is a matter of what the individual tasks are and what the resources are. Your constraints will reflect the current setting.

Fixed duration: A week-long training course will take a week - it is a fixed duration, whether the course is attended by 1 person or 100 people.

Fixed units: You could move 100 boxes of chocolates from the store to the shop by asking: 1 person to move all 100 boxes might take an hour; 2 people to move 50 boxes each would take half an hour. You can double the resources, get the job done in half the time, but you will still have used your resources for 1 hour.

Fixed work: You need to move 100 boxes. No matter how many people you put on the task, or how they do it, they could walk, they could run, they could throw them along a chain gang, the team will only ever be able to move 100 boxes because that is all that is there to move.

Make the changes to tasks individually based on those rules and your knowledge of the project at hand.

Good luck
Russell
