If a parent member has one child member, and you tag the child as Dynamic Calc, you must also tag the parent as Dynamic Calc. Similarly, if you tag the child as Dynamic Calc and Store, you must also tag the parent as Dynamic Calc and Store. However, if a parent member has one child member, and the parent is a Dynamic Calc or Dynamic Calc and Store member, you do not have to tag the child as Dynamic Calc or Dynamic Calc and Store.
