System production levels are defined by numbers from 1 (least secure) to 5 (most secure). A system production level number is assigned when your system is installed. To seeyour system production level, check Data-Admin-System.

When you enter one of these numbers beside an access control or privilege, you are specifying the highest production level on which the role can perform the operation. For example, if users can perform an operation on a production system (level 5), then they can also perform that operation on all systems having lower security (levels 1 through 4) such as development or test systems.

This approach allows you to implement one class access model that provides more restrictive access for a given user in a production environment and less restrictive access in a less secure environment.
