Interaction with Licensing
There are three license types: named user, concurrent session, and business process cycle, which is used in combination with named user licensing. Concurrent session licensing is checked at log-in. Named user licensing is verified in User Maintenance.
For a named user license, the system counts the number of active users authorized to access the licensed application and compares the number against a predefined limit for the license.
If the number of active users exceeds the predefined limit specified in the license agreement, a violation message displays in User Maintenance. Violation messages can be either warnings or errors, depending on whether enforcement of the license policy is implemented. Errors prohibit actions in User Maintenance when the limit on license agreements is reached; warnings allow actions to continue.
See Registering Licenses.
System administrators can implement enforcement of license agreements by setting the Enforce Licensed User Count field to Yes in Security Control (36.3.24). Setting this field determines whether:
Errors or warnings display in User Maintenance.
System administrators can create new users when the number of existing users exceeds the licensed number.
Additional users can log in when the number of sessions exceeds the licensed number.
The applications a user can access must be activated for the user. You can activate access to applications here or when you register an application license code in License Registration (36.16.10.1). This includes the base application. If a user ID is obsolete, you should inactivate access to all registered applications.
