Working with a Pivot Table, we know that each row or column dax calculate 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, dax calculate, the Pivot Table will take each month in the report and apply it as a filter to the entire dataset.

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.

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. It contains all the details in that thread. Firstly, these are the mistakes that are committed in the data model including measures -. And when you iterate over the entire fact table they provide an unexpected results which are hard to trace. See how -.

And therefore, results are evaluated correctly. The Measures respect the original Pivot Dax calculate filters year and monththen apply additional filters. These remaining rows in the table are then aggregated in this example, summed to produce a single value result, i.

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.

In Power BI, there is a common combination of DAX functions that allow us to create a dynamic cumulative total on any report page. The CALCULATE function allows you to change the context of a calculation within a measure wherein the context is coming from the environment where your calculation is being done. The ability to change the context within a measure is very important in DAX. Think about how you can apply this on something that you are working on.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. DAX formulas include functions, operators, and values to perform advanced calculations and queries on data in related tables and columns in tabular data models. This article provides only a basic introduction to the most important concepts in DAX. It describes DAX as it applies to all the products that use it. Some functionality may not apply to certain products or use cases. Refer to your product's documentation describing its particular implementation of DAX. DAX formulas are used in measures, calculated columns, calculated tables, and row-level security. Measures are dynamic calculation formulas where the results change depending on context. Measures are used in reporting that support combining and filtering model data by using multiple attributes such as a Power BI report or Excel PivotTable or PivotChart.

Google Sheets. It removes filters from the Sales Order table Channel column. Iterator Not recommended The use of this function is not recommended. Note that when a model measure is used in row context, context transition is automatic. So at the back-end, Power BI engine by default evaluates the measure and converts it into like this -. Volatile A volatile function may return a different result every time you call it, even if you provide the same arguments. Think of the short syntax as being a convenient way for humans to read the expression. All the filters are intersected together, regardless of the order in which they appear. It is hard!

Featured Course Automate With Power Query — Recipes to solve business data challenges Do you want to become more confident using Power Query and automate your entire data workflow? 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.
