After you have data in your catalog, and (optionally) have customized review display column and configured reasons for review actions by accessing the Configuration menu; you can begin creating reviews. This is where a set of reviewers examine who has access to what in their environment. Administrators can create review definitions for the following types of objects:
Access permissions, accounts, or technical roles of a set of users
Unmapped accounts
Accounts, which includes both mapped and unmapped accounts, and optionally, the permissions assigned to the accounts
Membership of a set of business roles
Identity attributes that were previously configured as available for reviews
Management assignments, specifically direct reports of supervisors
Only users with the Review Administrator or Global Administrator authorization can create and modify review definitions.
