Does Dynamic Access Control (DAC) restrict users from seeing object values in the Document Properties in Vault?
No. Users are able to see values for the affected object field in the Document Properties. Users cannot hover over any object value and see the details of the object value if they are restricted by DAC rules.
A Vault Owner user is able to view these details along with users who are not restricted by Dynamic Access Control on the affected object.
