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.

Creation of Calculation View

  1. Create a new Calculation View.

    Yes Joseph ,

    you can model the solution..

    Currently is no hierarchy support similar to NetWeaver or BW in HANA but you can model the solution from the scratch.

    Thanks Mahesh,

    I am new to SAP and HANA Studio; can you please guide me on how to build standard cost center/profit center hierarchy in HANA Studio database using SETLEAF, SETNODE AND SETHEADER? I will need to implement this in attribute view and connect it to GLPCA for GR55 profit and Loss statement report. Below is my attribute view for the profit center/Cost center hierarchy. The issue with this model is that I can only move two levels down the hierarchy.

    Model
    Dim_Profit_Center_Hierarchy using inner join to join Setleaf, setnode and setheader using setnode.setname

    Analytic views on GLPCA join CEPT (RPRCTR), CSKT(KOSTL) and DIMCOST_PROFIT(VALFROM)
