• Key Concepts: 
  A calculation view is a type of data model in SAP HANA that combines different types of data sources, such as tables, views, and other calculation views. It is used to define complex calculations and logic, and to create a single virtual data model that can be used for reporting and analysis. 
  
  How to use it: 
  Calculation views can be created in the SAP HANA Modeler perspective of the SAP HANA Studio. The view is created by dragging and dropping data sources onto the canvas, and then defining the logic and calculations that should be applied to the data. Once the view is created, it can be used in reporting tools such as SAP BusinessObjects or SAP Lumira. 
  
  Tips & Tricks: 
  When creating a calculation view, it is important to consider the performance of the view. This can be done by using the Performance Analysis tool in SAP HANA Studio to identify any potential bottlenecks in the view. Additionally, it is important to consider how the view will be used when designing it, as this will help ensure that it meets the requirements of the end user.
