I have seen that while there are no restrictions to the number of users that can access a particular view at a given point of time, there can be certain settings at server level that can allow only a particular number of requests. For example, your configuration for concurrent number of queries at server level can have an impact in such situations. Also, any similar restriction defined in the Resource Manager can affect the number of users. You can modify these restrictions to suit your need.
You can refer to [Limiting Number of Concurrent Queries]( https://community.denodo.com/docs/html/browse/7.0/vdp/administration/server_administration_-_configuring_the_server/limiting_the_number_of_concurrent_requests/limiting_the_number_of_concurrent_requests) and [Resource Manager]( https://community.denodo.com/docs/html/browse/latest/vdp/vql/resource_manager/resource_manager) for more information.
Hope this helps!
