Remove filters from one or more columns, or from all columns of a single table.

The use of this parameter is not recommended. This parameter is deprecated and its use is not recommended. CALCULATE ( [, [, [, … ] ] ] ), This site is protected by reCAPTCHA and the Google. All explicit filter arguments are evaluated independently in the original evaluation context. They cannot use functions that scan or return a table, including aggregation functions. Order of Evaluation in CALCULATE Parameters. For each column used in a filter argument, any existing filters on that column are removed, and the filter used in the filter argument is applied instead. The use of this function is not recommended. Click to read more. There's also the CALCULATETABLE function. The expression used as the first parameter is essentially the same as a measure. A new filter is added to the Product table Color column—or, the filter overwrites any filter that's already applied to the column. It performs exactly the same functionality, except it modifies the filter context applied to an expression that returns a table object. 2018-2020 © SQLBI. » Read more, 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. Evaluates an expression in a context that is modified by the specified filters. If there are no row contexts active, this step is skipped. Information coming from MSDN is property of Microsoft Corp. SQLBI is a trademark of SQLBI Corp. https://docs.microsoft.com/en-us/dax/calculate-function-dax. Please, report it us! It discards the original row contexts, because the new evaluation context will not contain any row context. This is important in order to avoid unexpected results with complex calculations made in filter arguments. 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. When the input parameter is a column name, a single column table. That means all conditions must be TRUE at the same time. It's the CALCULATE function that modifies the filter context by using the REMOVEFILTERS function, which is a filter modifier function. Once all implicit filters created by the context transition are applied to the new filter context, CALCULATE moves on to the next step. CALCULATE evaluates the CALCULATE modifiers used in filter arguments: CALCULATE applies the explicit filter arguments evaluated at 1. to the new filter context generated after step 4.

An expression cannot use a nested CALCULATE function.

In this example, row context is converted to the filter context. Row context Examples in this article can be added to the Power BI Desktop sample model. There are several rules that they must abide by: A table expression filter applies a table object as a filter.

This scenario can happen in a calculated column formula or when an expression in an iterator function is evaluated. Once this evaluation is finished, CALCULATE starts building the new filter context. It removes filters from the Sales Order table Channel column. Jump to the Alternatives section to see the function to use. The value that is the result of the expression. CALCULATE performs the context transition.

This article describes the options available to create complex filters in DAX. They provide you with additional control when modifying filter context.

DAX Filter - CALCULATE function - Evaluates an expression in a context that is modified by the specified filters. Finding the right granularity for it is important to control the result and the performance.

The following Customer table calculated column definition classifies customers into a loyalty class. This function is deprecated. (Optional) Boolean expressions or table expressions that defines filters, or filter modifier functions. » Read more, Expanded tables are the core of DAX; understanding how they work is of paramount importance.

Filter functions. The filter context generated after point (5) is the new filter context used by CALCULATE in the evaluation of its expression. A boolean (True/False) expression or a table expression that defines a filter. Evaluates an expression in a modified filter context. Modify filter direction (from both to single, or from single to both) or disable a relationship. The following Sales table measure definition produces a revenue result, but only for products that have the color blue. To calculate the ratio of current reseller sales to all reseller sales, you add to the PivotTable a measure that calculates the sum of sales for the current cell (the numerator), and then divides that sum by the total sales for all resellers (the denominator). An expression cannot reference a calculated field. Filter modification functions allow you to do more than simply add filters. This article describes the options available to create complex filters in DAX. It could be a reference to a model table, but more likely it's a function that returns a table object. It's required when an expression (not a model measure) that summarizes model data needs to be evaluated in row context. » Read more, A filter argument in CALCULATE is always an iterator. The value is the result of the expression evaluated in a modified filter context. The CALCULATE function evaluates the sum of the Sales table Sales Amount column in a modified filter context. If the columns (or tables) are already in the filter context, the existing filters will be overwritten by the new filters to evaluate the CALCULATE expression. Click to read more. When there are multiple filters, they're evaluated by using the AND logical operator. CALCULATETABLE function » Read more, Last update: Oct 13, 2020   » Contribute   » Show contributors, Contributors: Alberto Ferrari, Marco Russo, MSDN documentation: https://docs.microsoft.com/en-us/dax/calculate-function-dax. They cannot use a nested CALCULATE function. For each filter expression, there are two possible standard outcomes when the filter expression is not wrapped in the KEEPFILTERS function: The CALCULATE function used without filters achieves a specific requirement.

There is no guarantee that the new filter context contains a single row at this point.

This includes both the original row contexts (if any) and the original filter context. Evaluates an expression in a context modified by filters. Note that when a model measure is used in row context, context transition is automatic. Add filter without removing existing filters on the same columns. If the REMOVEFILTERS function is supported by your tool, it's better to use it to remove filters. Filter context

Did you find any issue? 1 The ALL function and its variants behave as both filter modifiers and as functions that return table objects. See Remarks and Related functions for alternatives.

This article provides a theoretical foundation of what expanded tables are, along with fundamental concepts useful when reading DAX code. 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. It uses the current value of columns in the original row contexts to provide a filter with a unique value for all the columns currently being iterated in the original row contexts. If the data has been filtered, the CALCULATE function changes the context in which the data is filtered, and evaluates the expression in the new context that you specify. A filter argument overrides the existing corresponding filters over the same column(s), unless it is embedded within KEEPFILTERS. » Read more. By default, when relying on more than one slicer they are considered in an AND condition. If the data has been filtered, the CALCULATE function changes the context in which the data is filtered, and evaluates the expression in the new context that you specify. Remove all filters, or filters from one or more columns of a table, or from all columns of a single table. All submissions will be evaluated for possible updates of the content. These filter arguments are applied to the new filter context once the context transition has happened so they can overwrite it, after filter removal — their filter is not removed by any. CALCULATE makes a copy of the original filter context to prepare the new filter context. Want to improve the content of CALCULATE? This filter may or may not contain one individual row. The value that is the result of the expression. The most important functions in DAX are […] » Read more, This article describes how to implement in DAX a logical OR condition between the selection of two slicers of a Power BI report or of a PivotTable in Excel.

When filter expressions are provided, the CALCULATE function modifies the filter context to evaluate the expression. An expression cannot use any function that scans a table or returns a table, including aggregation functions. This expression is executed in a Row Context. The expression used as the first parameter is essentially the same as a calculated field. The ALLEXCEPT function removes filters from all Customer table columns except the CustomerKey column.

The following Sales table measure definition produces a ratio of sales over sales for all sales channels. All rights are reserved. For example, the predicate shown in the first expression is internally converted in the second expression. It's a very simple scenario: When the revenue produced by the customer is less than $2500, they're classified as Low; otherwise they're High. 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. This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules. Learn more about CALCULATE in the following articles: This article explains how the context transition interacts with the filter arguments of a CALCULATE function in DAX. Engage an inactive relationship between related columns, in which case the active relationship will automatically become inactive.
