After installing DataSync for ServiceNow, the application installs a role called perspectium that has access to the Perspectium application's tables. This role can be used to limit ServiceNow users to only have access to the Perspectium application and can be given to a user used with the DataSync Agent to access ServiceNow table schemas in order to replicate accurately and dynamically to external databases. If you want to assign a user a read only access to the Perspectium application, a perspectium_readonly is also available.
See Assign user a role in ServiceNow to add the perspectium or perspectium_readonly role to specific user.
