Project provides you with many ways to record actual information. Typically, when you enter tracking information in one field, Project calculates values for other fields. For example, if you enter a percentage complete for a task, Project calculates and supplies an actual start date, an actual duration, a remaining duration, and an actual work value.
As you record tracking information, Project adjusts your project’s cost to reflect the effect of higher-than-expected costs. And, if Project determines that you’re running late on a task, it automatically moves dependent tasks into the future.
