This is an intentional limitation of the Qlik Sense Desktop. If you upgrade to the full Qlik Sense product then you can schedule reloads and drive reloads of external actions (e.g. database update etc.). Business users would log into to a web browser to access Qlik Sense and the data would update automatically in the background. If you'd like to try out the online experience you can either upload your app to Qlik Cloud (www.qlikcloud.com) or take a look at the Qlik Sense Demo site (Qlik Demos: See Qlik Sense in Action | Sense-Demo.Qlik.Com). You can't reload on either of course but they will give you an idea of what the online experience is like (don't forget to give a try with a phone or tablet as well).
