Maybe I posted my challenge in the wrong forum so I add a link here

"I would like to have your input on a challenge I'm facing. Normally what if analysis as shown by Qlik is just about scaling a measure. This is about "moving" values in the data like using addmonths() in the script answering what if we produce this order 1 month earlier and another 2 months later?

I've been thinking about
- on demand app generation (ODAG)
- extensions which modifies the underlying data-set so all charts are updated in a session
- mashups with crossfilter and own charts.
I attached a simple qvf to show how it could look like."
