Hands-On SQL Server 2019 Analysis Services

By: Steve Hughes

Overview of this book

SQL Server Analysis Services (SSAS) continues to be a leading enterprise-scale toolset, enabling customers to deliver data and analytics across large datasets with great performance. This book will help you understand MS SQL Server 2019’s new features and improvements, especially when it comes to SSAS. First, you’ll cover a quick overview of SQL Server 2019, learn how to choose the right analytical model to use, and understand their key differences. You’ll then explore how to create a multi-dimensional model with SSAS and expand on that model with MDX. Next, you’ll create and deploy a tabular model using Microsoft Visual Studio and Management Studio. You'll learn when and how to use both tabular and multi-dimensional model types, how to deploy and configure your servers to support them, and design principles that are relevant to each model. The book comes packed with tips and tricks to build measures, optimize your design, and interact with models using Excel and Power BI. All this will help you visualize data to gain useful insights and make better decisions. Finally, you’ll discover practices and tools for securing and maintaining your models once they are deployed. By the end of this MS SQL Server book, you’ll be able to choose the right model and build and deploy it to support the analytical needs of your business.

Adding measures to Power BI when using tabular models and live connections

As we saw earlier, with the lack of support for the hierarchy slicer, new measures can only be added to tabular models when using a live connection. This functionality is not supported with multidimensional models. In this section, we will add a measure to our tabular model report. This allows us to expand on the model without changing the underlying model. Let's begin:

  1. Open your tabular model Power BI report.
  2. Add a new page to the report so we have a clean design canvas to work with. Select the Sales table as we will be adding a Total Quantity measure there.
  3. There are two standard ways to create new measures in your report. On the Home ribbon, you can see the Calculations section, which has two buttons – New measure and Quick measure. We will start by creating a simple new measure. First, click New measure:
