cannot change a start date on a task


P

Peter

I have a task that has the following attributes:
Fixed work (effort driven)
A predecor or a milestone task (so no resource assoicated with the pred task)
no other linked tasks
A resource assigned with plenty of availblity - no over allocation
Situation:
The task had a constain of "Start no ealier than" and a start date somewhere
months ahead so the time between milestone end and task start is significant.

I changed the attribute of the task to "Start as soon as possible" thinking
that it would collapse this time.
The result is no matter how matter what I do to try and change the start
date of this task it will not take - period. There is nothing indicating
that the Resource is causing this odd restriction.
There is one oddity: out of desparation I changed the attribute of the task
to "Must Start On" and a Link warning popped up. What is off is that there
are no more links to this task - period.
Did I just run into a corrupt piece of data?
Do have to rebuild the task (delete and re-add it from scratch)?
Why is this occuring? Any know bugs out there regarding this?

Look for an entry in the "Actual Start" field. Or, make sure all your
%Complete fields are 0% for that task. Did that help?

Peter,
First you might try suggestions listed in FAQ 50 on our MVP website at,
http://www.mvps.org/project/faqs.htm

If that doesn't help, you may have a corrupt file. Then you can try
suggestions in FAQ 43

Hope this helps.

Hi Jim;
Nope - that didn't help - and BTW those fields were empty anyway. I'm
thinking I am coming across something corrupt.

John - would you please update that link to the document? I can't seem to
find it on the Microsoft Site...

Thanks

Please verify the following:

From the toolbar, Select Project, Project Information, Schedule from

If you are scheduling from Finish date, this will cause difficulties in changing task dates. Change the schedule from to Start date and you should be able to change the selected task dates.

Hi
Open Views,Resource sheet and make sure your resources are at the same calender!

Sorry I'm so late to the party, but I just ran across this same scenario in a plan that I administer. I was able to get my stubborn task to move by changing the Calculate option to Manual (Tools>Options, Calculation tab, Calculation mode: Manual)

This did resolve my problem for this specific task, though I do not know what other impacts this change may have on the rest of this plan.

Hi .... make sure that there is no predecessor at the task summary level, this will create conflict in the schedule

This solution worked for me. There was a forgotten dependency in a task summary three levels up.
