Following this post which talks about methods for configuring apps, this post looks at how to achieve this via the QMC in QlikView and set variables in reloaded QVWs.
You’ll need to have Publisher enabled to access the features used for this example.
In a QlikView deployment with Publisher you’ll have access to the Reload tab for a task. This includes the option to add Script Parameters, which essentially leads to duplicate apps based on the provided field or variable name.
However – provide just one variable value, and you’ll pass this into one copy of the app.
