I wondered if anyone can tell me why the Data manager take so long to load?
I converted a Qlikview App to Qlik Sense and the script executed perfectly. After that I opened up the Data manger to see how the tables are linked but it has nearly been 4 hours since I started this action and it is still "Loading tables..."
The Data Manager works best/fastest with low amount of data because it has to scan your whole model. The Data Manager is analyzing not only the meta data, but also the data it self. That is why it can suggest for example the best joins/links.
My suggestion would be to use the Data Modelviewer for this.
