@sudheersakamuri Well, I don't work for Qlik, but if you'd like my two cents...
1) Billing any tool as a self-service tool always strikes me as a bit disingenuous. It's only self service after someone has done all the legwork of prepping the data and metadata. Rather like self-cleaning ovens, which are called self-cleaning because you clean them yourself.
2) Professional users can do exactly what you describe, almost without limitations (since they can use their own objects and formulas). They're really only limited by what data has been included in the app.
3) Analyzer users can have access to multiple levels of what one would typically consider "self service", depending on your app structure.
* Insight Advisor's natural language is IMO not great at all, but it does offer the ability to create tables and graphs by checking the relevant fields from the master item list, which IMO is 100% self service.
* Things like Alternative measure and dimensions, cyclic groups, or ad-hoc tables (which are easy enough to make in Qlik) provide another layer of self-service, which is enhanced by the ability to bookmark the result's layout and revisit it later without the need to create your own sheets or objects.
* Extensions exist that improve on the standard self-service capability. A good example is Vizlib Self Service / Custom Report.
Where Analyzer is somewhat lacking is in the ability to save, reuse, and/or share your self-service analysis, but to be fair, that's kind of the point of having two license types in the first place. Even then, you can work around this by having a Professional user create the layout and then switch the owner in QMC.
