The setting 'Allowed Document roles to update Periodic Review' refers to the roles - i.e. Author, Reviewer, Approver, QA - who have the right to change the periodic review when the Document is in Published status. QA is allowed to do this by default but you can customize this on your end by adding whichever roles you see fit.
To update the roles, follow these steps
- Go to Scilife Settings > Permission Settings.
- Select Documents.
- Update the role(s) in the Allowed Document roles to update Periodic Review.
