Here is how you can utilize Qlik Sense’s custom properties to govern access to data connections, streams, extensions, and/or content libraries at a group level.
First create a custom property:
Next, add custom property to your resource.
Then add the appropriate custom properties to your users.
Lastly create a security rule:
((user.@Group=resource.@Group))
This basically says to allow any user with a custom property that matches the custom property on the data connection read access.
Super simple and clean, and just a glimpse into the power of security rules.
