Calculation Groups in DAX – first impressions
Microsoft announced at SqlBits a very important feature for DAX: Calculation Groups. These are my first impression about the new feature and the impact it will have on Analysis Services and Power BI.
The Calculation Groups provide the ability to create items that are displayed to the users as values of a column. Each of these values can apply changes to the evaluation of a measure, enabling calculation like time intelligence (year-to-date, year-over-year) to existing measures without having to enable new measures.
