Duration Calculation

[Jimmy]

How can I make the sub task duration calculate for the sub task only.
Currently each sub task is adding itself to the previous making my three month
project appear to be a year long?

Hi Jimmy,

Welcome to this Microsoft Project newsgroup

A summary task gives a summary only of those subtasks under it. Its
Duration is a measure of the working time from the start of the first task
to the finish of the last task. How many levels of summary/subtask do you
have?

Hope this helps - please let us know how you get on

Glenn, I have 118 task which have about 5 sub task each. each task is about
the same amount of days, but each task is adding the days from the previous
task
to it. my first task = 142 days the second is exactly the same but it
reports as 268
the third which the same as the first = 310

Hi Jimmy,

We seem to have some definition problems. Tasks are activities which help
towards the completion of the project - what you're calling sub-tasks.
Summaries are not tasks at all in that sense, but just summarise the tasks'
data that are outlined beneath the respective summary. This is more clearly
and diagrammatically explained in my series on Microsoft Project in the
TechTrax ezine, particularly #2 and the section called Outlining, at this
site: http://tinyurl.com/2xbhc or this:

(Perhaps you'd care to rate the article before leaving the site,
Thanks.)

That being said, unless you have more outline levels of summaries within
summaries, each one should not be affected by the others. Is this something
that's just happened? Did you notice the summary totals changing as you
indented to create the summaries? Maybe we have some corruption here. Does
this happen with a new project?
