Calculation View Intro:

Calculation views are composite views used on top of analytic and attribute views.

Calculation views combine different fact tables

Calculation views are defined as either graphical views or scripted views depending on how they are created

Graphical views can be modeled using the graphical modeling features of the SAP HANA Modeler

Scripted views are created as sequences of SQL statements.

Typically used when the business use case requires advanced logic that is not covered in the previous types of information views

For example, calculation views can have layers of calculation logic, can include measures sourced from multiple source tables, can include advanced SQL logic, and so on

The data foundation of the calculation view can include any combination of tables, column views, attribute views and analytic views.

You can create joins, unions, projections, and aggregation levels on the sources.
