Hi,
For this scenario on restricting user to create not more than certain number of views, I would [develop custom Stored Procedure](https://community.denodo.com/docs/html/browse/7.0/vdp/developer/developing_extensions/developing_stored_procedures/developing_stored_procedures#developing-stored-procedures) and the Denodo Platform provides examples of stored procedures and their source code. They are located in <DENODO_HOME>/samples/vdp/storedProcedures. The README file in this path contains instructions to compile and install them.
Additionally, if you still need help and if you are a valid Support User, you may open a Support Case at the [Denodo Support Site](https://support.denodo.com/) and the Support Team will help you.
Hope this helps!
