Changing Project Task Planned End Date not Changing Parent Planned End Date

[gfancher]

Occasionally when a Project Manger changes the Planned End Date on a child Project Task the parent is not being updated to that date, even though it is the latest date of all the child tasks. I'm wondering if there is a scenario where this is the intended behavior.

Are you properties set up correctly?

Does this happen to just the planned end date?
