Calculation Views (HANA)Locate this document in the navigation structure

A calculation view can perform complex calculations and can have tables, standard views, and other calculation views as sources.

Context

PowerDesigner support for generation and reverse-engineering of calculation views depends on the deployment environment:

Deployment Environment

Repository

HDI

Creation/Generation (see Exporting Objects to the HANA Repository)

Simple Views (1-2 sources) – Generation of complete calculation view to repository.

Complex Views (>2 sources) – Generation of sources, projection list, and n-1 joins to repository.

Simple Views (1-2 sources) – Generation of complete calculation view to HDI file.

Complex Views (>2 sources) – Generation of sources, projection list, and n-1 joins to HDI file.

Reverse-Engineering (see Importing Objects from the HANA Repository)

Read-only XML definition and projection list of calculation view linked to sources (tables, standard views, and calculation views) for inclusion in impact analysis.

Not supported.

In this section:
    Creating a Calculation View
    PowerDesigner supports creation of calculation views for export to HANA. Simple calculation views with one or two data sources can be designed within PowerDesigner, while more complex calculation views with three or more data sources can be initialized for completion within your HANA modeling tool.
    Importing Calculation Views
    PowerDesigner supports reverse-engineering of read-only calculation views for inclusion in impact analyses.
