Project planning

I've created my project, created numerous activities with Validated Times on them... and everything was looking good.

Then I must have done something that messed it up... now all my activities in this one project have the planned start and end dates of today.. and were showing 0 hours of work left, even though there were 0 hours of real work and I had validated work for each one. It also caused my project to show 100% completed.. when it wasn't..

I went in to the Real Work Allocation screen and was able to set the left work to match how much the validated work for each activity, so that then fixed the left work and the percentage complete, but I still have the planned start and end dates set, which I think is really messing up my planning.

So the question is... how can I clear the planned start and end dates for my activities?

Also, any idea what I did so I can make sure I don't do it again?

Thanks,
Dan

After playing around a little more, I think that you are correct, I might have done that.

Would that explain why all my Projects/Tasks ended up with 0 hours remaining? (effectively all completed?)

Also is there a way to reset the start dates and the time remaining instead of having to go through and set the remaining hours on each item?
