Qlikview is for "personal" analytics. SSAS is for designed for a broader range : from "workgroup" analytics up to "enterprise" level.

I have just helped a client (Fortune 100) recover from a Qlikview binge that saw them deploy it across their enterprise, only to find the the "in-memory" solution does not scale at all! In fact, its utterly useless for large data footprints. Instead it works for small data sets that a single user might analyse on their own PC. With MS PowerPivot, its entirely possible now to replicate that functionatliy of Qlikview in Excel for free.

If you want some real power use SSAS and you'll be able to support hundreds if not thousands of users without any of the Qlikview hang ups. Complement the engine with a good client tool for viewing the cubes (like Pyramid Analytics) and your end users will never look back.
