If you want to present a report based on data, you will do so by connecting to the source, purifying, modeling it and then adding appropriate visualizations. As part of the modeling process, we often created measures and calculated columns by writing DAX statements. In a similar way, we were able to add Quick Measures. Now there is an even easier way, and that is to create calculations within a visual…
Calculation groups is a new option within the Power BI Desktop application that allows us to implement DAX calculation groups within the data model. They serve to simplify calculations when we use similar DAX expressions, where only the variable (expression) that appears in them varies. By adding them, the model is automatically optimized by removing implicit measures.
Reporting dimensions are all fields that you can see in the Fields menu, which are used to populate reports. Basically, these are the columns in the table model. Also, they can be Calculated Columns or Measures. In some earlier “recipes” I talked about how to create them in PowerPivot model, and now I will show you how to do perform this in PowerBI Desktop. Also, I will mention another interesting novelty: Calculated Tables!
In one of the earlier posts I wrote about that PowerBI comes in many “flavors”: as a Cloud Service (PowerBI.com) as a development environment (PowerBI Desktop), as application for mobile devices available on Windows, Android and iOS platforms (PowerBI Mobile). Since the majority of you who are reading these lines deal with reports development I decided to demonstrate you, in a practical example, how to use PowerBI Desktop.
KPI (Key Performance Indicator) is the most common factor that shows the success of the company in any sphere of business, such as financial performance, customer confidence, employee satisfaction, process management … In Power Pivot reports KPI is obtained by comparing the existing measures with a goal value or another measure. When dragged in the report KPI is presented as a value, goal or status indicator (traffic light) showing whether the target is exceeded, realized or unrealized.
