Checks ancillaries to verify compliance with the rules and application defaults.
An ancillary chosen via rules is always valid at the moment of selection. However, it is still important to understand why it was selected and to verify future model or rule changes do not invalidate it.

Check the results for unset defaults

To navigate to the component in the Model Explorer and view its properties, right-click in the table and select Component Reference.
