In the official Cloud Documentation I found a described methodology to change the behavior by using a Business Rule: Enterprise Item Number Business Rules - User Assistance R2022x (3ds.com). Unfortunately I know that since R2022x, the usage of Server BL´s on Public Cloud are nor more supported. In addtion there is the hint, to use the "Data Model Customization app" for implementing Creating Enterprise Item Number Business Rules - User Assistance R2022x (3ds.com), but this APP is only available in the role TXO, which is not available on Cloud, not on public, nor on private.

But if I upgrade the excisting Ressource Set oder creating a new one, I found the functionality in the Engineering Release Ressouces Tablle.

So I am confused about the possibilities and limitations, starting with R2022x . In R2021x war was no limitations, so we created a BL´s which works fine. What should / could be do to ensure the needed functionality with no regression.
