I have seen this requirement in many QV Developer positions. What exactly are they expecting from this particular req. Is it the familiarity with different versions of Qlikview. If it is so, they want to know what different changes QV versions went through, say from 2008 to 2014 or something.... If any one can shed some light, that would be great
Not sure.. haven't seen the post. But from a capability standpoint you can have the QlikView server host several historical version of the QVW (from previous reloads) . There are RAM considerations in doing this. It may be worth adding a 'version' dimension to the QVW which could add data , but may compress better.
