Why is the opt-in setting of an enabled functional area or feature read-only?

The opt-in setting of a functional area or feature is shown as read-only due to one of the following two reasons:

• If a functional area or feature represents a core functionality of the offering, it automatically inherits the enabled or disabled status of its parent.

• The opt-in setting of the functional area or feature may be locked once enabled due to the business operation it represents.
