What is a Named CAL? What is the difference between User Cal, Usage Cal and Session Cal?
The IE Plugin doesn't allow to change documents, rather than, if any, create or modify shared object (with the Enterprise Edition server license).
Document CALs can be checked either looking for a user in the QlikView Enterprise Management Console or selecting the different documents available, a tab "Document CALs" will appear on the right side.
Any user with security permissions granted to modify the file and that has QlikView Desktop installed is able to modify the document. If you want to avoid User CAL assigned users to do that, then you need to add a section access in your document, or make it available only by client (AJAX, Plugin, etc).
Re: What is a Named CAL? What is the difference between User Cal, Usage Cal and Session Cal?
That means you have 180 users who have dedicated licenses. All of these people can access simultaneously, but it needs to be these specific users.
The 20 session CALs are additional concurrent users, not tied to specific user names. So besides the 180 dedicated users, you can have an additional 20 users on the system at any given time. When one of the concurrent Session CAL users leaves the application, the session CAL will be made available should another user connect.
