When you login to DistillerSR and notice that in your top menu there are only limited options (e.g. Review, Reports, and nothing else), this is due to the Project-related permissions assigned to you by your Account or Project Administrator.
By limiting the screens accessible to different users in the Project, users can focus on their assigned work (e.g. only reviewing references, or generating specific reports) and there is less of a chance of something being changed in a different screen (e.g. someone accidentally modifying Level Settings or deleting a Form from the review).
If you require access to a specific screen, your Administrator can adjust your permissions in the DistillerSR Permission Matrix.
