Plan Viz is a built-in SAP HANA performance tool that provides information about the runtime of specific queries on data models. The layering of views should generally have no performance impact in and of itself, but this is not entirely correct in all situations. I have read about performance blogs, where we can push down the filters at the base table of the calculation view by using input parameters. Calculation views can be created in a graphical user interface (like the other views) or as the result of a SQL script query.
