The class level recursion described previously is unnecessarily complex and inefficient for most requirements; instead of using class level recursion, it is usually more sensible to sequence the derivation calculations on each class.

In the example given previously of a delivery cost, that is derived based on state, and on state being converted into uppercase, you would set a lower sequence for the state derivation, and a higher sequence for the delivery cost derivation. This way, the state is always derived before the delivery cost, preventing the need for class recursion.

Generally, Recurse Levels should be set for each class, if derivation sequencing is set, in order to improve efficiency. Setting Recurse Levels to 1, turns off class level recursion for that class.
