Thank you for your feedback on ways to improve our product. While this is something we understand would be useful, it's not on the short-term roadmap. Please continue to show your support for this idea.
This request is something that one of our clients has been raising regularly for some time now. A use case for this is a meeting taking place reviewing e.g. outstanding sales orders, and after cancelling or updating an order, wanting to refresh the app to see the effect. Currently we are also using an extension to achieve this, but it takes some effort to set up and would obviously be preferable if it were native functionality.
We are currently using the reload button extension in many Qlik Sense reports to allow users dynamically search on a small set of data from large table. It takes the input values as parameters and applies the user entered selections to query the data from source tables directly. It will be very useful to support on-demand reload functionality in Qlik.
ODAG generates and loads new app based on the user selections, that's more convenient than reload which replaces the existing app the current users settings.
