Hi again,

found a new amazing feature in Project that I don't get

I have set up a project plan and all plan dates incl. dependencies look fine. Now as soon as I enter any value in the % completion field of the first task, the plan finish date changes to a later date. Why?

For the following tasks, no such issue occurs. It's just that single task.
Also, this will happen on any value, i.e. even if I set 90% with which we'd be ahead of plan, it'll change.
