Part.Unitprice and .InternalUnitPrice

Using Vantage 8.03.404a, is there any internal logic, or trigger that updates these two prices (Part.Unitprice and Part.InternalUnitPrice) in the part master automatically?
I'm going under the assumption that these 2 numbers will not change unless I go in and change them myself.

Also, do you know if anything is triggered when you change them in part master?

thank you for any answers.
