i have an idea or for some situations the solution as well:
In Qlik Sense we dont have any triggers, i mean, if you move from one tab into another tab, you want sometime to have a pre-selected values in your fields, for this situation i created a mini-solution.
for this case you need an extension, this extension i finded in: (look at this link: Qlik Branch)
the extension is called: SheetEvents: if you downloaded make the following necessary steps:
in Tab Action (within Extension): Select Action: Select Value in Field and tip your data. / Alternative: you can use the Action: Apply Bookmark (here you should create a bookmark)
p.s: in attached file you see what i mean and see tab: nummer 1. this extension does work great on Qlik Sense Server as well
i hope that helps and save your time in your business-field.
