What is HA300 SAP HANA Modeling and Why You Should Learn It
HA300 SAP HANA Modeling is a course that teaches you how to create calculation views using the SAP Web IDE for SAP HANA. Calculation views are the core of data modeling in SAP HANA, as they allow you to combine data from different sources, apply filters, aggregations, hierarchies, currency conversions, and other functions to create analytical applications.
What is HA300 SAP HANA Modeling and Why You Should Learn It
In this course, you will learn how to use different types of nodes, such as projection, join, aggregation, rank, and star join, to design calculation views. You will also learn how to use SQL and SQLScript to query and manipulate data in SAP HANA. Additionally, you will learn how to optimize your models for performance and security, as well as how to manage and migrate your modeling content using projects and GIT.
By taking this course, you will gain the skills and knowledge to develop effective and efficient data models for SAP HANA 2.0 SPS06. You will also be prepared for the certification exam C_HANAIMP_17 - SAP Certified Application Associate - SAP HANA 2.0 (SPS05), which validates your ability to implement and model SAP HANA solutions.

You can also access the self-paced e-learning version of the course with an active subscription to the SAP Learning Hub.
In this section, we will look at some of the benefits of using calculation views in SAP HANA. Calculation views are flexible and powerful tools that enable you to:
Access data from multiple sources, such as tables, views, functions, procedures, and remote data sources.
Apply complex business logic and calculations to your data, such as filters, aggregations, hierarchies, currency conversions, time-based dimensions, and more.
Create analytical models that can be consumed by various applications and tools, such as SAP Analytics Cloud, SAP BusinessObjects BI Platform, SAP Lumira, SAP Data Warehouse Cloud, and more.
Optimize the performance and security of your models by using features such as static cache, parallelization, union pruning, analytic privileges, data masking, and data anonymization.
As you can see, calculation views are essential for creating data models that meet the needs of your business scenarios and users. In the next section, we will show you how to create a simple calculation view using the SAP Web IDE for SAP HANA.
To create a calculation view, you need to use the SAP Web IDE for SAP HANA, which is a web-based development environment that allows you to design, develop, test, and deploy SAP HANA applications. You can access the SAP Web IDE for SAP HANA from your browser by using the following URL: https://:/sap/hana/ide/
Once you log in to the SAP Web IDE for SAP HANA, you will see a workspace where you can create and manage your projects and files. To create a new calculation view, you need to right-click on the src folder of your project and choose New > Calculation View. You will then see a dialog box where you can enter the name and description of your calculation view, as well as choose the type of view (dimension or cube) and the data category (default or time).
After you click on Create, you will see the graphical modeler of the calculation view, where you can drag and drop nodes from the palette to the canvas and connect them with wires. You can also configure the properties of each node, such as the data source, the join type, the aggregation function, the filters, the variables, and more. You can also switch to the SQL mode to see and edit the SQL code of your calculation view.
To test and deploy your calculation view, you need to save and build your project. You can then preview the data of your calculation view by right-clicking on it and choosing Data Preview. You can also use the SQL console to execute SQL queries against your calculation view. To make your calculation view available to other applications and tools, you need to grant the appropriate privileges to the users or roles that need to access it. 04f6b60f66
