In SAP HANA, what type of view is typically used for reporting purposes?

The choice of a calculation view for reporting purposes in SAP HANA is based on its ability to perform complex calculations, aggregations, and transformations on data. Calculation views can incorporate data from multiple sources, including both tables and other views, making them highly versatile for reporting requirements.

These views can enable users to create intricate data models that can be tailored for specific reporting needs. For example, you can utilize a calculation view to combine sales data with customer information, applying necessary filters and aggregations to present the data in a meaningful way.

In contrast, a projection view is primarily used to expose a subset of columns from a single table without performing complex calculations. While it simplifies the structure of the data model, it is generally not sufficient for advanced reporting needs.

The graphical view is simply a visual representation of the calculation process but does not define any new logic or performs calculations itself.

A table function, on the other hand, is used to define reusable logic that can be executed to produce a table-like result set, but it lacks the direct approach for handling reporting scenarios that calculation views provide.

Therefore, calculation views stand out as the favored choice when dealing with reporting due to their flexibility and capability to dynamically aggregate and manipulate data according to user requirements.
