We are working with a project schedule that is populated with tasks and resources, and in some cases, money. Is there a way to "go back in time" and see what the status was at some given point in time, prior to today? Changing the current date does not do this as far as we can tell. Surely, we could, at the end of a month or work period, save a copy of the schedule, rename it, and keep it, but this seems inefficient and we'll soon have dozens of schedules for different periods. Thanks.

You may have as many as 11 different baselines capturing start, finish, duration, cost, and work. You can save the baselines as needed to capture "point in time" information.

Thanks. That helps going forward, but I suppose there's no good way to do it going backwards, is there?

No, sorry. There isn't any way back machine in Project :-)
