How we can do Incremental Load in Qlik? Is it possible without having QVDs?
Incremental load in Qlikview
you can save to text file but there is not real benefit of this.
You could use partial reloads - Qlik Sense Partial Reload for v2.0.x and v2.1.1
Though I'd question why you don't want to store QVD's. They are pretty useful in a situation such as this.
