Then recreating as calculation groups so you can add all your other metrics without having to copy and paste the same measures over and over again

You can imagine starting a prototype model with DAX for a specific metric. The base DAX in this data set can now be added into Tabular Editor Scalar function – a function that returns one single value Instead of having to recreate this DAX over all your ID’s where necessary you only need to do it once The measure is replaced with the scalar function SELECTEDMEASURE() Total Sales is a measure created with SUM() using the Sales Amount metric from the data source In this example, go back to the original pbix and copy a time intelligence DAX measure YTD Sales = TOTALYTD(,DimDate) Right click Calculation items and choose new calculation item Along with this I may have other base calculations like Distinct Count of IDs to make a number of events. I initially recreate all the metrics from source as SUMs so they can be used within measures. The rows are based on all the calculation items that I already have in this model. What has been created is essentially a single column table. This example is renamed to time Intelligence. The best example to look at is time intelligence Create New and Calculation Group Time Intelligence You are taken straight to the model you are connected to

You must enable Store datasets using enhanced metadata format in Options > Preview features.

You must have them installed at the right version for this to work.

The SolutionĪs from July 2020 you can reach tabular editor Via External tools Its actually quite fiddly so adding the first lot of DAX required always takes a lot of time. The same measures are repeated over and over again for the different metrics in the report.Īnd adding metrics in Power BI desktop isn’t a fast process. Each one has to be added to Year to Date, Last month, last Year, Month to date etc metrics. There are metrics for number of events, Financial metrics, timing metrics. Taking one of our current pbix files as an example. Now Tabular editor Lets you build calculation groups for Power BI. Expressions consist of values, operators and constants.Calculation groups look like a game changer, but are they? These have been available for Analysis Services tabular models for a while. That trend continues, because of simplicity and fast query execution (related to DirectQuery mode in SSAS Tabular).ĭAX query consists of a function and number of expressions (e.g.):įunctions are the main part of the query, and they act similar to some T-SQL statements (as we will see later).

Note: Don’t get confused with DAX code presence in a MDX query – both of them, DAX and MDX, can query a Tabular model database.ĭAX originally emerged from a Power Pivot add-in for Excel, as a formula language extension for creating calculated columns and measures for data analysis (which are also integral elements of one SSAS Tabular model database, too), but when Microsoft added support for DAX queries in SQL Server 2012, BI experts started “daxing” data from Tabular model databases. Querying a SSAS Tabular model database in this article will perform in SSMS, within the MDX query window, as shown in the picture:

In order to get insight in a Tabular model database, the main method is data retrieval from tables through queries after that, performing additional simple or complex calculations can take place. Requirements for querying with DAX include SQL Server Management Studio 2014 or higher with an installed SSAS Tabular instance, and a deployed SSAS Tabular model database. In this article, we will learn some basics of querying a SSAS Tabular model database with simple DAX queries, starting with a theoretical approach, and then retrieve data and analyze it.

To make the first steps into the BI world easier, you just need to build one SSAS Tabular model database.
