The correct procedure for implementing currency conversion on a measure within an SAP HANA Calculation View begins with defining the column's semantics. The measure must be assigned the semantic type "Amount with Currency Code" to link it to its corresponding currency unit column. Following this, the conversion feature is explicitly enabled for that specific measure. The final step involves configuring the conversion parameters, which includes specifying the source and target currencies, the client, the conversion date, and the exchange rate type to be used for the lookup in the currency tables (e.g., TCURV, TCURR, TCURX).

A: Defining an expression in a calculated column is a manual approach; SAP HANA provides a built-in, optimized engine for currency conversion that does not require manual expressions.

B: The conversion logic is configured directly on the properties of a specific measure, not as a separate rule that is assigned to the entire calculation view.

D: This option is less precise. "Build the conversion rule" is a vague description of the configuration steps that are explicitly and correctly detailed in option C.

SAP HANA Database Modeling Guide for SAP Business Application Studio

Section: "Model Business Scenarios"

Subsection: "Converting Currencies in Calculation Views". This guide explicitly states

"To convert currencies

you must first assign the semantic type

Amount with Currency Code to the measure... In the properties pane of the measure

set the Enable for Conversion toggle button to ON." It then details the configuration of source/target currency

conversion date

and rate type.

2. SAP HANA Modeling Guide (for SAP HANA Platform)

Section: "Creating Calculation Views"

Subsection: "Applying Currency Conversion". This document outlines the same prerequisite: "In the Semantics node of the view

select a measure... and assign the semantic type Amount with Currency Code." It then describes enabling the conversion and setting the parameters like Target Currency

Exchange Rate Type

and Conversion Date.
