Unlock the Power of Power BI with Calculation Groups

You make a great data model in Power BI. It has calculations that are essential to the business. So much so that you get requests to create multiple versions of those measures such as Month to Date, Quarter to Date, and Year to Date. With the multiple variations of each measure in the model it has increased the complexity.

One solution to this problem is Calculation Groups. Calculation Groups in Power BI allow you to separate out the MTD, YTD, and QTD logic and reuse the measures you already created. Calculation Groups’ primary goal is to make DAX code less complicated. It allows users to display the variations for each measure in a report.

We will cover how to create Calculation Groups in Power BI and cover best practices. After attending this session, you will know how to:
• Create calculation groups
• Use multiple Calculation Groups in the same model
• Employ best practices when using Calculation Groups

Basics of building a data model in Power BI

So, you want to start using Power BI. You have a couple of data sources that you want to bring in. How do you go about bringing in this data? How do you build a data model out of this data?

This can be a daunting task and one we will tackle from the beginning. First, we will look at using Power Query to bring in the data. Then we will examine how to best create the data model.

We will cover some of the best practices when developing the data model so that it scales well. One of the benefits of having a well-designed model is the DAX code can be easier to understand.

Power BI and External Tools: This is the way!

Much like an adventurer roaming the galaxy – Power BI is better when it is not a solo traveler. What lies beneath the tab in Power BI named external tools, there are a lot of choices to consider, each has their own strengths and weaknesses.

These tools offer the ability to execute queries against the model, gather insights about your data model, and make changes to the data model separate from Power BI Desktop.

This session will cover an overview of the tools available, so you don’t spend a lot of time straying from the path.
