Can't Find Constraining Tasks

[Gary Furash]

I'm working with a fairly complex merged project. Every
so often updating tasks yields "x is linked to a task
that cannot move..." However, I can't find the linked
task that is causing the problem.

Is there a macro or utility out there that will trace
this?

Don't you just love those "informative" error messages? I get this one all
the time and regularly ignore it. It seems to be saying that "Gee, I will
have to move a successor (in another file) to the right in order to satisfy
the link's logic." So, since that is what I want anyway, click OK and carry
on.

Now, if there is a better interpretation or explanation, I too am
interested.

Hi Gary,

Welcome to this Microsoft Project newsgroup

My interpretation is similar except that I presume the successor task is not
moved. This will create an overallocation at that time. Scrolling through
the Resource graph or one of the Usage views for Red fonts should reveal
where the problem lies.

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

Take a look under the mene series - Project, Filters, More Filters and apply
the "Tasks with fixed dates" filter. That will show the tasks that have
constraints and may help you track down the source of your problem.

Thanks all. I wrote a recursive set of VBA classes that,
given a task, find all its parents, pred., & succ.,
iteratively until it's scanned the plan, then identify
those that have constraints. It worked great and found
the distantly related task that was acting as the
constraint.

If anyone wants it, its free - no guarantee of usability
or anything.
