Entity &1 has no access controls from which to inherit

What causes this issue?

You have used the expression INHERITING CONDITIONS FROM ENTITY &V1& to
inherit roles from entity &V1& and apply them in the current access
control. However, this entity does not have access controls and hence no
conditions from which to inherit.
While the runtime behavior for entity &V1& is full access, this
situation in the current access control results in an error message to
avoid giving full authorization by accident (for example by typing
error).

System Response

You cannot activate the current access control.

How to fix this error?

You can suppress this error by explicitly specifying that it is to be
expected that the inheriting entity &V1& does not have access controls.
By specifying DEFAULT TRUE, you can declare that the expression shall be
treated as a TRUE boolean predicate, by specifying DEFAULT FALSE that is
shall be considered a FALSE boolean predicate.
A TRUE predicate as final expression result gives full access, a FALSE
predicate blocks access to the entity.
