Changing my dates in Project

[Refreshing]

Hello, I'm Refreshing.. and it's been a very very long time since I've use
Project and I've forgotten how to use the product. I inherited a 7000 line
file that was created by someone who is no longer here. I recently had to
change about 700 task in the file in which I did by cutting and pasting. I
then went back and reset the predecessors starting at the top with Phase I.
Some of them changed, but not all. Now here's the problem I need to change
many of the dates starts and finishes, but project is not allowing it.

All but a few task have a contraint type of ASAP, I have a few with SNET and
I using two calendars. When I try to set the dates all of the dates start to
move.

If you are trying to reset dates on a summary task, Project will not allow
it. Those are derived by dates in the subtasks whcihc you should be able to
change.

In your 2nd paragragh I get confused. Because then you say all the dates
start to move. This would be correct behavior if a date on a predecssor
changes, and it has other successor tasks linked to it with an ASAP
constraint (and Auto Calculation is turned on).

If I am not reading your post correctly, please see if you can help with
more information or further questions.

Hi,

This is an urgency. Find a course immediately or start reading a book
tonight. A 7000 task project in the hands of a novice..; You must have
hundreds of questions, and how will you see the relationship between the
answers?

Good luck (somebody else is trying to answer your posts)

Of course the task dats will move - that what Project exists to do, ie,
calculate dates based on task durations, predecessor relationships, and
resource availability. You should be more worried if the the dates DON'T
move on their own or if you are trying to set the dates yourself and it lets
you do it because both of those behaviors indicates that something is very,
very wrong.

In the best of worlds, the only date you input into Project is the Project
Start date, the kickoff, and from there Project tells you when you should be
expecting to be able to do all the rest of the tasks in the Project. You
don't tell it the dates you expect to do tasks - it tells you the dates you
can reasonably expect to be able to do them.
