If you’re new to Qlik Sense, start with this Discussion Board and get up-to-speed quickly.
I did fresh install of Qlik Sense Desktop and create my first app. I add some table in-app manualy and also connect to one data source (Oracle DB). Everything work except Data model viewer. This option is (in left upper menu) still disabled. I can not access it. Any idea?
This just happened to me. I then realized that I dropped all the tables in the load (because it's a transform load in an ETL process). Not an answer, but just in case this happens to someone else.
Let me summarized, Data model viewer button enable only when there is data in dashboard.
So in first case he did not reload dashboard because of that there is no data in dashboard.
In 2nd case( @howiekrauth ), He reload dashboard but drop all the tables in the end, it means at end of script again there is no data in dashboard.
