Hi Benedict,
I tried and it doesn't work. I thought like we could use them using CE_JOIN_VIEW statement but it turns out we can use only Column Views in here.
So you can also use your Column Views in SQL Script.
So i would say that SQL VIews are SQL functionality so they still exist here.
As we can create HANA Views for Reporting, similarly we can create these SQL Views and perform analysis using Data Preview - it has no limitations of Attribute or Analytic View like Fact Table, Master Table.
