When a filter argument has the form of a predicate with a single column reference, the expression is embedded into a FILTER expression that filters all the values of dax calculate referenced column.

Here we introduce its base behaviors, with a solid theoretical foundation. Last note before we start: it is impossible to properly understand the details of CALCULATE without a proper understanding of the row context , the filter context and the context transition. If you are not familiar with these concepts, we suggest that you read these articles and gain some practice, then come back to this article. For example, the following measure computes the sales amount of Red products:. When used in a matrix, the filter over Product[Color] is added to the already-existing filter placed by the matrix itself on the Product[Brand] column. In the first column, when Product[Brand] is in the filter context filtering Contoso, the Sales Amount measure computes the sales amount for Contoso products.

Hey all, Can someone please explain to me why the Sumx measure in my model is not right. As you can see in my example I tried setting up measures to help sum by shipping type inbound, outbound, stat. I know that the Sumx measures are wrong and the calculate ones are right. I thought in my Sumx measures I know that it is iterating thanks to my coursework! As you can see in my example that is not the case and the numbers are, for the most part, WAY off. It is interesting on the lower counts of shipments about 12 or less the 2 types of measures Calculate and SumX do still produce the same results??? Thanks in advance m Shipping example. I would sincerely recommend you to please go through that thread for more better and in-depth understanding. Below is the link of that thread provided for the reference. So at the back-end, Power BI engine by default evaluates the measure and converts it into like this -. And therefore, results are evaluated correctly.

Other Apps, dax calculate. Dax calculate into Excel, AI and other essential tech news: carefully crafted for the modern professional. The reason why this happens is because Power BI is not able to identify any unquie values for each row and therefore, it consider them as one single group.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. It performs exactly the same functionality, except it modifies the filter context applied to an expression that returns a table object. There are several rules that they must abide by:. A table expression filter applies a table object as a filter. It could be a reference to a model table, but more likely it's a function that returns a table object. You can use the FILTER function to apply complex filter conditions, including those that cannot be defined by a Boolean filter expression. Filter modifier functions allow you to do more than simply add filters.

Working with a Pivot Table, we know that each row or column in a Pivot Table report act as a filter for the entire data set. If we have a table of daily sales and we create a Pivot Table report showing total sales by month, the Pivot Table will take each month in the report and apply it as a filter to the entire dataset. The result of each filter is a reduced version of the whole. These remaining rows in the table are then aggregated in this example, summed to produce a single value result, i. Think of it as refining the original Pivot Table or replacing certain aspects of the original Pivot Table with different aspects to tell the story a different way. Calculate can overwrite all existing filters or supplement the existing filters with other filters. The Measures respect the original Pivot Table filters year and month , then apply additional filters. The results are the only part of the process we can see. Next, we filter the [Quantity] column to only include entries that are greater than I'm a 6x Microsoft MVP with over 15 years of experience implementing and professionals on Management Information Systems of different sizes and nature.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The DAX function reference provides detailed information including syntax, parameters, return values, and examples for each of the over functions used in Data Analysis Expression DAX formulas. New DAX functions - These functions are new or are existing functions that have been significantly updated. Aggregation functions - These functions calculate a scalar value such as count, sum, average, minimum, or maximum for all rows in a column or table as defined by the expression. Filter functions - These functions help you return specific data types, look up values in related tables, and filter by related values.

Context transition. Did you find any issue? Fast Track to Power BI. Shipping example - Harsh. For every row, the filter introduced by the matrix is the corresponding color Black, Blue, Brown…. Deprecated This parameter is deprecated and its use is not recommended. Here we introduce its base behaviors, with a solid theoretical foundation. Table of contents. LinkedIn Twitter YouTube. The filter replacement happens only when the same column is present in both the outer and the inner filter. DAX is the new language used by PowerPivot and Analysis Services in Tabular mode and it resembles the syntax of Excel formula and it can be considered a functional language. Indeed, even though we use conditions, the DAX engine transforms conditions into tables.

When a filter argument has the form of a predicate with a single column reference, the expression is embedded into a FILTER expression that filters all the values of the referenced column.

Context transition -- 3. In this article, we introduce this optimization with some examples. By default, when relying on more than one slicer they are considered in an AND condition. The relationship is defined by naming, as arguments, the two columns that serve as endpoints. Expanded tables are the core of DAX; understanding how they work is of paramount importance.
