I just started a Udemy Course on QlikSense Analyics 3 days back, and I'm not quite sure if I've grasped the concept of dollar-sign expansions properly. The syntax is alright, but its purpose is still unclear to me esp. w.r.t. writing variable expressions in the data load editor. Help!
P.S. Can't find a dedicated sub for Qlik Sense, hence I'm posting the question here.
