Hi Liz,

I'm afraid I don't follow your new question. By definition, duration is in working day - omitting non-working time such a Saturday and Sunday.

The man-hours you are referring to are usually called "work" and is based upon resources assigned to tasks. It is very possible to have a task with a fairly long duration but lower amounts of work.

The two complete fields are the % complete which is a duration field calculated = (Actual Duration/Duration)*100.

If you have a 10 day duration task, and you've complete 6 days, the percent % is 60%.

% Work complete is a work calculation:
(Actual Work/Work)*100

In most circumstances as % complete changes, % work complete would change as well. Where there may be a difference is a task that has a work contour where the task may start with 1 person but as the task progresses additional resources perform work.

I hope this helps.

Julie
