Permissions are not discussed much in the Calpendo User Guide because the Permissions that exist are completely configurable for the facility by the administrator and the user should not need to know much about them. A user will be subject to whatever Permissions have been set up for Calpendo, and the only way a user will know when something is not allowed is if the system prevents them from attempting to do something (such as greying out buttons that lead to actions that cannot be performed) or by giving an error pop-up that will say Permission Denied.
To know more about Permissions, then see the Permissions chapter.
