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, dax calculate, the Pivot Table will dax calculate 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.

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. Indeed, even though we use conditions, the DAX engine transforms conditions into tables.

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. They provide you with additional control when modifying filter context. It transitions row context to filter context. It's required when an expression not a model measure that summarizes model data needs to be evaluated in row context. This scenario can happen in a calculated column formula or when an expression in an iterator function is evaluated.

I'm a 6x Microsoft MVP with over 15 years of experience implementing and professionals on Management Information Systems of different dax calculate and nature. Hey all, Can someone please explain to me why the Sumx measure in my model is not right, dax calculate.

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???

Indeed, even though we use conditions, the DAX engine transforms conditions into tables. The previous code can be written in the following, equivalent way:.

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.

As you can see in my example that is not the case and the numbers are, for the most part, WAY off. Understanding the difference between a row context and a filter context is the first and most important concept to learn to use DAX correctly. So see, how that exact same measure is evaluated at the back-end of the Power BI engine. 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??? Harsh December 6, , am 4. The result is obviously smaller than Red Sales , as it takes fewer rows in the Sales table into account. There was an error submitting your subscription. Here we introduce its base behaviors, with a solid theoretical foundation. Shipping example - Harsh. This is important in order to avoid unexpected results with complex calculations made in filter arguments. To get the model, see DAX sample model. They provide you with additional control when modifying filter context. My passion is teaching, experimenting and sharing. If the outer filter context contains a filter for blue products for example, then FILTER iterates over only the blue products.

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. For example, the predicate shown in the first expression is internally converted in the second expression.

As you see, the value of sales for the red products is repeated in all the rows. It's required when an expression not a model measure that summarizes model data needs to be evaluated in row context. Optional Boolean expressions or table expressions that defines filters, or filter modifier functions. As you can see in my example I tried setting up measures to help sum by shipping type inbound, outbound, stat. The following Sales table measure definition produces a revenue result, but only for products that have the color blue. This article provides a theoretical foundation of what expanded tables are, along with fundamental concepts useful when reading DAX code. Please, report it us! Not recommended The use of this parameter is not recommended. The DIVIDE function divides an expression that sums of the Sales table Sales Amount column value in the filter context by the same expression in a modified filter context. Thanks and Warm Regards, Harsh. You can appreciate the difference between Red Sales and Red Sales Keepfilters in the following matrix.
