I'm using the latest edition of Q1IM V7.1
The tasks 'Configure Role Assignments' is not available for Role Class.
I refer to the documentation, it should be there.
To configure secondary assignment to roles of a role class
1. Select the role class under Basic configuration data | Role classes.
2. Select the task Configure role assignments.
3. Use the column Allow assignments to specify whether assignment is generally allowed.
NOTE: You can only reset the option Assignment allowed if there are no assignments of the
respective objects to roles of this role class and none can arise through existing dynamic roles.
4. Use the column Allow direct assignments to specify whether a direct assignment is allowed.
NOTE: You can only reset the option Direct assignment allowed if there are no direct
assignments of the respective objects to roles of this role class.
5. Save the changes.
