Durations appear to be changing at random
in [Project]

From: Sherri on 3 Aug 2006 13:51 Hi there, I'm hoping there's an easy solution to this problem...all of my project schedules appear to have the same issue. The problem: fixed duration tasks are increasing their duration when changes are made to (seemingly) unrelated tasks. Example: Task A has a duration of 10 days. MS project has changed the duration to 12.38 days. When the duration is reduced back to 10 days, a warning message appears saying that Task X has had its duration increased to accomodate the change made to Task A. When I investigate what has happened to Task X, usually the duration has increased (quite significantly), say from 10 days to 26 days. When Task X is returned to its 10 day duration, the same warning message appears for a different task, and so the domino effect goes through the project until I've exhausted all of the tasks. As far as I can tell, none of these tasks are directly related to one another and there is no logical reason for a change in duration of one task to affect the duration of another. To add to the misery, it doesn't always warn me that it's changing a duration elsewhere in the project. help - it's wreaking havoc on my completion dates. Thanks. Sherri

From: "JulieS" passport6847 at maine dot rr dot on 3 Aug 2006 15:09 Hi Sherri, It may be an issue related to non-working time for resources. Project will change the duration of a fixed duration task to accommodate a change in resource calendars. If you are changing durations of Task X and it is linked to Task A, if Task A now falls into non-working time for a resource, the duration will change. I hope this helps. Let us know how you get along. Julie Visit http://project.mvps.org/ for FAQs and more information about Microsoft Project.

Thanks Julie, That's definitely part of it, the resource works a 4-day week, with 5 weeks on and 1 week off. The calendar has been set to reflect that, but the durations still exceed the length of time that should be scheduled even with the non-working time factored in. For example, the duration of a task A is 6 days long, but there are 4 non-working days that fall within that time, which should make the duration 10 days. The problem is that the duration is being set much higher, say 17 days. "JulieS" wrote: > Hi Sherri, > > It may be an issue related to non-working time for resources.
