When you login you will be requested to select both a product as well as a Workspace. A workspace will define where your files will go when you check your applications in/out.
When you select a product such as Qlik Sense or QlikView the Workspace you are able to select will filter based on your access rights to such workspace so if you don’t have the rights to access a workspace it will not be on the list to select. Should you require access to a workspace which is not on the list please contact your administrator.
