What Order Management & Pricing entities depend on item class changes in Oracle Cloud

We are currently migrating our item classification structure from a legacy system to Oracle Cloud. In our legacy setup, the parent item class was private, and we did not have any child item classes. For Oracle Cloud, we plan to make the parent item class public, create a child item class as private, and assign items to the child class.

Question:

What Order Management & Pricing entities in Oracle Cloud are dependent on the item class? Specifically, are there any considerations or impacts we should be aware of when changing the parent item class from private to public and introducing a private child item class for item creation?
