Failure to Calculate Consistantly Start/Finish Dates

[GHF]

This one has me stumped. I am trying to bulid a template file using SP3 from
an existing file.

Here are the conditions:

1. Calculation set to Automatic
2. % Complete is zero
3. The Predecessor dependency is FS with no lag or overlap
4. Constraint Date, Actual Start, and Actual Finish are NA
5. Duration is 1 day
6. Effort Driven is NO
7. No resources have been assigned
8. Work is 0 hours

In a running string of tasks under the same summary task

Task 251 - for example - will finish on 3 November, and its successor 252
will start on 24 November. A second task - 256 - will have the same
predecsssor (251) will start on 4 November.

If I change 252 to any other ID, then change the predecessor back to 251,
the problem resolves its self.

Any ideas?

Dear Microsoft Office Project User,

I understand from your question that two one-duration tasks [ID: 252, 256]
have the same predecessor [ID: 251].

Moreover, from your conditions indicated the calculation is automatic which
means the Start and Finish is calculated automatically.

I assume that you are moving one of these tasks and observe the dependencies
of the moved and and its surrounding tasks changes automatically.

To prevent this from occuring, you need to uncheck "Autolink inserted or
moved tasks" option under Tools > Options, Schedule tab.

If this option is checked, then inserted or moved tasks gets linked to its
surrounding tasks; otherwise Microsoft Office Project respects the moved task
and changes the affected tasks predecessor to the ID of the moved task.

Remember! This applies only to contiguous Finish to Start task relationships

Please let us know if this helps.

Hello George,

Based upon what you report (changing predecessor fixes the problem) my
*guess* (without seeing the file) is you have a mildly corrupted file.
On a copy, try following the steps outlined in FAQ 43 "Handling file
corruption and/or bloat" at
http://project.mvps.org/faqs.htm

I hope this helps. Let us know how you get along.
