TerryHolland,
Welcome to the "wonderful world" of Project...... :-)
First of all, don't confuse task duration with work. Duration is the
amount of working time, (as defined by the project calendar -
Project/Change Working Time), between the start of a task and the
finish. For summary lines, duration is NOT the sum of subtask durations,
unless all the subtasks just happen to be linked finish-to-start with no
lead or lag. For summary lines the duration is the working time from the
start of the first performance subtask to the finish of the last
performance subtask. "Performance" tasks are the real tasks wherein one
or more resources are assigned to complete it. Summary lines are NOT
performance tasks.
Work on the other hand is the effort required from one or more resources
to actually complete the task. If a single resource is assigned full
time to a given task, then the duration time and the work time will be
the same.
That's the short lesson, you might want to go to our MVP website at:
http://www.mvps.org/project/links.htm
and click the link to fellow MVP, Mike Glen's series on Project lessons
and techniques.
Given the above, there might not be a need for you to export to Excel at
all. What are you defining as "work units"? If it is the Work field,
Project already sums that up for you, and if it's not in the "cut" that
you want, it is likely the grouping feature of Project can be used to
provide the information. If you are really talking about duration, then
as stated above you do NOT want to simply sum things up.
Hope this helps.
