How to use RANKX to calculate the Dynamic Rankings in Power Pivot and Power BI July 10, 2017 July 16, 2017 The DAX language in Power BI has a function RANKX that returns a ranking of a number in a list of numbers for each row in the Table argument. Understanding context usage and utilizing it effectively is the most important DAX concept to grasp. Year 2013 Name So far the queries that we have created in DAX have focused on the entire result set (with the exception of the start at clause in evaluate). The CALCULATE function takes an aggregate function and a filter context. g an employee) in the filter context. …So we're essentially gonna replicate…what Excel is doing instantaneously…every time a measure gets calculated in a pivot table view. The existing filter context is defined by two factors: the slicer, which dictates that only the tasks A and C are to be included. For each cell in a pivot table, current members of row labels and column labels also add filters to filter context. Filter context is easily seen in your reports. For example, when you add TotalCost to a visualization, and then add Year and Region, you are defining a filter context that selects a subset of data based on a given year and region. The filter context for each value cell includes the items on the row labels, the column labels, the report filter, (and slicers when/if they are being used. This course will guide you to deep understanding about various concepts of DAX like filter context, row context, evaluation context, Table or scalar DAX functions, Iterator DAX functions, Calculated Measures, Calculated Columns, etc. In this article, I’ll explain what measures are, where and how to create them, and I’ll explain the difference between filter and row context in DAX. Ever struggled with a formula in DAX that does not compute what you want? the filter context applied to a calculation using a special DAX measure in Power BI  Filter context is the set of values allowed in each column, based on filter However, with DAX you can build a single formula that returns the correct value, and  Oct 17, 2018 Hi @frodriguezw. DAX Filter ALLSELECTED function - Learn DAX Functions in simple and easy steps starting from basic to advanced concepts with examples including Introduction, DAX Parameter Naming Conventions, Description Structure, Aggregation, Filter, Time Intelligence, Date and Time, Information, Logical, Mathematical and Trigonometric, Parent and Child, Statistical, Text, Other. Using the filter context, we can go over each line and calculate the intermediate result. Once all implicit filters created by the context transition are applied to the new filter context, CALCULATE moves on to the next step. For example you might want to calculate sum of sales amount for all "Red" products. Then make two measures that look at the date column, first measure would have a MAX(date), and the other would have a MIN(date). What you see is all due to filter context. The CALCULATE function performs two fundamental operations: it directly manipulates the filter context, and it converts an existing row context into an equivalent filter context. Apply the evaluation context to the underlying table. Filter Context. Understanding the row context. The following example shows how to generate different levels of visual totals in a table report using DAX expressions. Instructions. May 23, 2019 When writing and testing DAX formulas, it is important to understand the for each part of the formula; i. Apr 16, 2017 Filter context specifies filter constraints on the set of values allowed in a column Context transition occurs because TotalSales is a measure. We'll see the DAX in Power Pivot Advanced DAX Functions and Concepts  Nov 18, 2017 Unlike in Excel formula, DAX doesn't understand cells concept. 72” is the result of the following conditions: DAX interpretation – Filter Context Using Variables within DAX. the position in the matrix. A column reference intuitively means that you want to retrieve You always need to take into account the filter context in order to understand how DAX evaluates a formula. Understanding how the DAX engine calculates measure results. When you use a measure in a pivot table, for example, it produces different results for each cell because the same expression is evaluated over a different subset of the data. This article describes the options available to create complex filters in DAX. Row Context is the complement to Filter Context. The syntax rules used improves the readability of the expressions, read this article to learn more: Rules for DAX code formatting » Syntax You can format any DAX query and expression in the form: Row context: Row context means taking into account a specific row that has been filtered in a DAX expression. It may need tweaking to handle Using Context To Traverse Hierarchies In DAX July 28, 2016 July 28, 2016 Meagan Longoria My friend and coworker Melissa Coates (aka @sqlchick ) messaged me the other day to see if I could help with a DAX formula. , the slicer). 2. Say you wanted . To ensure the rank measure working at both parent-level and child-level, we need to calculate the rank accordingly depending on the what level the current filter context is at. An alternative could also be, just add a column for years, and then add the year column to a page or report filter. When to use. It can be used to clear filters from a filter context as part of a complex calculation, but it can also be used to generate and return a table. In this article we are going to slow things down a little and look at DAX COUNT and COUNTX – Impact of Using Measures and Columns. Here are definitions of each context. And it does this by evaluating both the current filter context and the filters applied by CALCULATE. A fundamental knowledge for authors of DAX measures is the filter context in which the calculation logic of DAX measures is executed. For example, to evaluate the DAX expression below, we need to iterate over rows in the Date table. This is why we get NULL values for all values except for the Southeast Sales Territory. The filter context is one of the two contexts that exist in DAX. In fact, Product[UnitPrice] used in the fifth row of the previous expression is the value of the unit price for the current row iterated by FILTER - our inner iteration. Let’s say you want to write a measure to calculate the total sales on red products. Filter context. Today, we're going to talk about another major component of DAX, Row Context. For example, the second line dictates that Employee = Bart and Task = C. this code is translated internally in DAX as following: Filter(All(StudentHistory[ClassType], StudentHistory[ExamStatus]), StudentHistory[ClassType] = "Audit" &&[ExamStatus] = "Resit") (All) is the filter remover. … Displaying filter context in Power BI Tooltips This article describes how to write DAX measures that compute aggregations or comparisons with past dates without showing or comparing future dates. For example, if you use a filter in a measure, and the measure is used in a PivotTable or PivotChart, the subset of data that is returned may be affected by additional filters or Slicers that the user has applied in the PivotTable. In a previous post, we talked about Filter Context, which is supplied by charts, slicers, and measures at runtime. you can achieve it by using SUMX or Calculate, and functions such as IF or Filter to write a conditional expression for product color to be equal to "Red". 4) DAX Measures (Calculated Fields) Filter Context. For Power BI DAX Measures, one of the hardest concepts to grasp is the Filter Context. Work Items and Tasks That said, DAX does not calculate the value this way, but first determines the corresponding filter criteria from the coordinates of the table and applies them together with the selected filters from the slicers to the data tables. If you haven’t, I encourage you to read it, as it contains a high-level overview of what PCC is. When one speaks of context, this may refer to one of the two types; Row context and Filter context. ♠ The Power BI DAX editor includes a suggestions feature, which helps you create syntactically correct formulas by suggesting you the right elements. If that is true, then the filter context can produce 'nothing' in your example IF your expression isn't ignoring the filter context (i. Many DAX functions have different behaviour in row context and filter context, like SUM: in row context, SUM sums all rows in the table, not only the current row; but in filter context, SUM sums only the rows in the filter context (and within FILTER this is only one A filter argument in CALCULATE is always an iterator. Here's one of the example measures: GrandTotal = CALCULATE(SUM('Demo Data'[Value]), ALL('Demo Data'[Category])) In the example I'm using a DAX function called CALCULATE to create three measures. Thus, DAX evaluates the expression inside a row context. e. When you need to clarify why a value is being returned as it is, or when you need to debug a result. See what happens, when I  CALCULATE & FILTER functions. Its companion is the row context and, in this section, you will learn what it is and how it works. This article uses the same simple database as its predecessor. The CALCULATE statement (passed as an argument to ADDCOLUMNS) transforms the row context (on Customers) into a filter context. We can use the DAX ISFILTERED function to evaluate current level. The easiest way to think about it is to actually walk through an example. #SQLSAT777 Understanding shadow filter context • Special filter context created by iterators which is always inactive except for certain situations • The DAX above generates a shadow filter context that contains the values of Product[Color] in the current filter context or explicit filter context when iterator starts. Top of Page. In essence what CALCULATE will do is modify the current filter context. Before we take a look at the CALCULATE function, let’s look at the concept of the ‘filter context‘ because it will be mentioned frequently during the walk-through and is one of the most important concepts of DAX. Context transition is the transformation of row contexts into an equivalent filter context. Consider a new measure [SalesWeek1] which references the [SalesTotal The original measure however keeps the original filter context when it calculates the temporary results table of the FILTER function. The row context focuses on the operation of the formula on the current row. The Filter Context is the set of filters that have been applied to a particular calculation. Welcome to the wonderful world of DAX! It is an interesting one. Filter context is the set of values allowed in each column, based on filter constraints that were applied to the row or that are defined by filter expressions within the formula. … Resolving Many to Many relationships leveraging DAX Cross Table Filtering Posted on 2012-05-08 by Gerhard Brueckl — 43 Comments ↓ If you ever had to deal with many-to-many relationships in PowerPivot then I am quite sure that you came across the blog-post Many-to-Many relationships in PowerPivot by Marco Russo and PowerPivot and Many to This is where my CALCULATE Debugger measure can help out: DAX CALCULATE Debugger. The Fact Table is filtered down to a smaller size iv. • Modifying Row & Filter context. DAX Rules for Evaluating Context Intersection of active rows on in-memory tables (including their relationships) DAX makes no assumptions for members omitted in formula Filters can use three types of contexts when deriving what rows qualify as active in a calculation: I. It helps if you have learned about filter context before but you should still follow the general idea outlined here without those knowledge. The most important step to understanding these functions is understanding contexts in DAX – what they are, how they interact, and when it is appropriate to create new contexts. A. The shaded lines in the formula below iterate over each row in the Sales table returned for the filter context, creating a row context the key concept in PowerPivot allowing you to use Excel-like functions to dynamically alter the criteria of each cell in a PivotTable. Marco has . The filter context is the set of rows for each table in the data model which are available to be evaluated for each value displayed in report visualizations. …So consider something simple like this Data Analysis Expressions (DAX) allow Microsoft Excel users to create powerful calculated fields in Power Pivot. MITCHELL PEARSON Dynamic Measure S19. Or is it? I explain the “Filter Context” with the 4-easy-step approach of the I. Therefore, the same formula, used in a PivotTable, is evaluated in a different query context for each cell. [Total Sales] is a measure and has an implicit CALCULATE. If you add additional fields to PivotTable, you need to add those fields to the ALL function to ignore the filter context in order to rank by multiple columns. Criteria from Row, Column, Filter & Slicer Areas filter the underlying Dimension Tables ii. • DAX function roadmap • CALCULATE & FILTER functions • How DAX Processes & Calculates Results • Dependent measures • Evolution of a measure • Modifying Row & Filter context • When to use iterators • DAX Studio DAX to the MAXX() Paul Turley Data Platform MVP, BI Consulting Architect Intelligent Business LLC Measure 2 = IF ( ISINSCOPE ( Sellers[Seller] ), TRUE () ) IsInScope can even detect more cases and cannot be expressed using any existing DAX functions which depends on the detection of filter context and/or the remaining column values after filters are applied. Which has performance issues. There is another important note in the previous formula. The syntax for CALCULATE is: =CALCULATE ([Expression], filter1, filter2…. DAX RankX() - Blank and ignore filter context Here is a potential measure that does this and works in the PivotTable you provided. 60 IsCurrentMonth False False False False False True True Return YTD Sales If the Typically, you use ISFILTERED or ISCROSSFILTERED. For DAX, the value “30’826. Row Context vs Filter Context (vs Query Context?) We mentioned table functions, iterators, row and filter context, measure, columns, and we also quickly introduced you to the RELATE function. The dynamic version of the ABC Classification pattern is an extension of the Dynamic Segmentation pattern. I read This measure reads “Sum the values according to the Filter context box, but first  Nov 22, 2017 One of the most challenging and useful DAX functions to master in Simply put, filter context is the selection of rows from various tables in your  May 8, 2018 Let me take a slight diversion from the DAX formula above. This type of context is most often applied to the measure rows. Rule; using a The CALCULATE function is the most important one in DAX. Finding the right granularity for it is important to control the result and the performance. The CALCULATE() function allows any DAX expression to be re-evaluated in a specified filter context and the ALL() function allows us to ignore all or some of the current filter context. • Dependent measures. N. Each of the filter parameters to CALCULATE() then modifies the filter context in the same way as the boolean case. transforms the row context (on Customers) into a filter context. In DAX In order to isolate those rows of data, you will be using filter context. Without understanding context, your solution may not be optimized to perform the best, may provide incorrect results, and may be too restrictive in its use. . Understanding the filter context applied to a measure in a Power BI report can be a challenging task. iv. Filter context is a thing that is almost automatically understood without thinking of it, but in some cases, mostly when working with DAX, you need to think more deeply about filter context. For a Fact Table We've seen that it can change the filter context, change a row context into a filter context, and can invisibly attach itself to a measure. Understanding the difference between row context and filter context is important in using DAX correctly. Principle. • Evolution of a measure. The question is – why use the RELATED function when the DAX formulae using filter context automatically link tables together? The answer is that within this formula, row context, not filter context, is used. Thanks to context transition, using a measure in the filter expression it is possible to filter a table based on a dynamic calculation involving other rows and/or tables. 582. If there are no row contexts active, this step is skipped. Solution. At the beginning, the stack is empty. Rank:=RANKX(All(Table1[Provider]),[TotalRevenue],,,Dense) If you had tried calculating the Pearson correlation coefficient (PCC) in DAX, you would have likely read Gerhard Brueckl’s excellent blog post. The Evaluation Context consists of a filter context and a row context, which are automatically defined in any query, for example by a pivot table in Excel. In the example above (Figure 2), the DAX engine is selecting high-priced inventory, or where 'Sales'[Cost Bucket]="High". Naturally, we would want to restrict the rowset in some way and this is the focus of this post - how to filter row-set tables in DAX queries. It really simplifies building measures if you understand it. Your formula does not make sense: unless Calendar[Month] is the unique date column, it is not going to function correctly. Row Context is used when you are creating calculated columns within your data model. Less General Definition of Filter Context = Conditions / Criteria / Filters (Synonyms) that filter the tables in the Data Model, so the Expression can use the filtered, smaller tables and columns as the source data to make the calculation. Then when your calculating other measures you would use the min and max dates as filter context. This article introduces these two concepts. Also referred to as evaluation context, DAX context is used to determine the evaluation of a DAX formula and the corresponding result. Example. • How DAX Processes & Calculates Results. However, the expression uses a FILTER that creates a new row context on the same table. Instead of relying on the PivotTable’s built-in process of creating a criteria based on the row value, column value, report filter, and/or slicer, utilize DAX functions to define the criteria. In other words, the row context within FILTER is replaced by a filter context. If the current filter context already has a filter on the column, it replaces it, otherwise it adds a new filter. The Data Analysis Expressions (DAX) language is a formula language for Power Pivot, Power BI Desktop, and Tabular modeling in SQL Server Analysis Services (SSAS), which allows users to define custom calculations in PowerPivot tables (calculated columns) and in Excel PivotTables (measures). In my example, I’m ranking by provider so the DAX function is using ALL function to ignore the filter context on Provider field. In your example, CALCULATE will compute the measure [X] using the existing filter context, except that it removes any existing filter context for FactTable[Color] and replaces it with FactTable[Color] = Red. Also, there is an extra close parentheses around (calendar[Month]), and the reference to Sales_Measure inside CALCULATE is missing square bracket delimiters. Oct 22, 2013 LASTDATE is a dax function that receives an argument that has to be a date column and returns the last date active in the current filter context. As the rank measure is calculated at the parent-level, it will not work at the child-level. But let’s say I wanted to filter out entire States where the average sighting length was > 6. DAX Measures & Filter Context: 1. Context is one of the most important of the 3 DAX concepts. Filter context and operators: Intersect You have 2 filter context, and you want to intersect them in a new filter context (that is to put them in what we called a logical AND) Intersect is the operator that CALCULATE uses when it needs to merge together filters that you create as a separate filter parameter in the statement. I hope this blog post got you thinking about Row and filter context in PowerPivot. On the Home ribbon click the New Measure button and enter but only calculate this value when a filter context from a different The ALL function in DAX is useful for two things. In the previous expression, Sales[Amount] and Sales[TotalCost] are column references. This is where DAX measures come in. The ALL() function removes all filters in the current filter context, hence CALCULATETABLE adds a filter and then ALL() removes it. Since I don’t have a column in my States table that does that, it’s sensible to use the measure, and that forces me to use FILTER, because FILTER does allow me to use measures in my comparisons: CALCULATE([Sightings per Year], Ignore that you would probably do that in a Measure First, realize that if you throw down a MAX() into a calculated column… it will evaluate over the entire table. What is filter context? There are two types of contexts in DAX. Setting a basic filter is one of the first things people do when writing a DAX measure. If it's in a measure (calculated field) it's not clear to me what you are doing with "other table" in the EARLIER statement. This concludes our overview of the DAX formula language. The point was that the filter context created… spans multiple tables. What is filter context? It is a little confusing if you are coming from an excel background. The purpose of the DAX CALCULATE function is to modify the Evaluation Context of  What is PowerPivot? Which versions of Excel contain PowerPivot; What is Data Model? . C. The Filter Context is a set of active rows in all the tables of the data model that are considered while evaluating a DAX expression. It groups items (such as Products or Customers) into segments based on their cumulated sales and how much they contributed to the total sales across all items. The second task is to develop and test a DAX measure which calculates the latest value in a fact table for the specific dimension member (e. I'm looking to create a Calculate DAX formula and I'd like to filter for any items in a list that I could type into the DAX code. In this course—the third and final installment of the Excel Business Intelligence series—experienced Excel trainer Chris Dutton spells out how to use the DAX language and Power Pivot to explore and analyze relational data models. Why is filter context so important to DAX? Because while filter context can most easily be applied by adding fields In DAX, context is an important term that you should be aware of, while writing DAX formulas. Note: The filter expression is affected by the context in which it is used. Learn more about FILTER in the following articles: Filtering Tables in DAX One of the core concepts is filter context. DAX Filter Context Confusing Totals. Filter Context I’m not a consultant and I don’t hate DAX, but having learned and worked extensively with DAX in the last few years, I can share why I’m sometimes frustrated with DAX. The MAX() function doesn’t care if you have a row context… it is expecting a filter context… and doesn’t find one and so, parties on the whole table. Or is it? I explain the “Filter Context” using the 4-easy step approach of the I. - [Instructor] Let's take a minute and really drive home…this idea of filter context by walking through…a step-by-step measure calculation behind the scenes. 120. This is how the ALL function is being used. You will draw upon your beginner DAX skills to delve deeper into the real meaning behind “Initial Filter Context”, “Filter Context” and “Context Transition” with explanations, diagrams, examples and practice exercises. Hi MIguel. There is no guarantee that the new filter context contains a single row at this point. For a Dimension Table Filter: i. The lookup functions work by using tables and relationships, like a database. This blog is part of our online SSAS Tabular tutorial; we also offer lots of other Analysis Services training resources. So Test 2 above first applies a filter to the Products table (Products[Category] = “Clothing”) as the filter parameter of CALCUALTETABLE and then the last thing it does is execute the ALL() Parameter. Visualising Context Transition & Extended Tables in DAX in DAX to deliberately or explicitly change the Filter Context. This blog shows you how to use it to replace, remove and amend the query context for a measure (and also explains what this sentence means!). The Filter Flows Across the Relationship iii. There wasn’t really a specific measure I wanted to show here — rather my updated understanding of how “filters” (probably not exactly the right term here) are applied when converting a row context to a filter context. In the example above (Figure 3), this means that Power BI is filtering 'Sales'[Order Total] only for high-priced inventory. This is a measure that returns a text-value, showing the number of rows of the adjusted filter context table, the MIN and MAX value of the selected column as well as up to the first 10 values. CALCULATE is important, because it overcomes the limitations of using FILTER and ALL, when they are used to manipulate a filter context on their own. Because of the implicit CALCULATE, the filter context on the single customer propagates through the relationship from the one side to the many side. Simple Example of how DAX Measure evaluates using Filter Context (file used for example:: 1. You have to evaluate the sum of the SalesAmount measure for each customer in the iteration defined by the ADDCOLUMNS function. Slicing and filtering operations also affect context. Is there any way to filter for a list of items? What functions would you use? I want the filter to work so that if the value matches any item in the list, that row gets included in the final result (sum aggregation). For each Date row, we need to evaluate the measure TotalSales, and then calculate the average of daily sales. ) As you can see we need context in a a lot of situations, even when you don’t know it. , no output), it sounds like the filter/slicer's has a beginning date that falls after the patient's discharge date. Key concepts around measure calculation: Every measure result is evaluated independently The filter context is the set of filters applied to the data model before the evaluation of a DAX expression starts. It will assign the CALCULATE result to all [ExamDate] in the initial filter context. Guess which one looks correct for the typical end user? The original measure of course. ) If you have created a calculated column, the row context consists of the values in each individual row and values in columns that are related to the current row. Context. The DAX query optimizer handles this very efficiently and this works well when you are detecting one fairly simple filter context like “did I filter by product subcategory?” However, when you are detecting thousands of different grain rollups, this approach will be impossible to code and Aug 30, 2015 Understanding the difference between row context and filter context is in a DAX measure, you get an error because no row context exists. When using calculate in complex situations, you should always make sure you can understand what it's doing and how it's performing. In row context, we Although the CALCULATE function is by more useful (and often easier to understand), DAX programmers should also learn about the FILTER function. The syntax above is internally transformed in the following one, which you Given the adjustment to the filter context is yielding zero (i. Query Context III. Create a Measure – gets evaluated every time your visual needs to be evaluated again with a filter like Calendar[Date]= TODAY() or using TODAY() in conjunction with other time intelligence functions to evaluate the TODAY() value and use it as you please in your Filter Context Re: Medians and context issues in DAX I took a look at the formula, but it's not clear to me whether it's a measure (calculated field) or a calculated column. Examine the evaluation context. Therefore, this new row context DAX has many functions to write conditional expressions. This article shows how you can use the FILTER function to do something similar and explains the This filter may or may not contain one individual row. Filter Context i. CALCULATE in DAX is such a powerful and complex function to fully understand. A filter context might be defined as the specific set of data an expression is evaluated against, after all participating The filter context from 1, flows into each of the filter parameters passed to CALCULATE(). May 8, 2012 Calculate function performs the following operations: 1. Row Context II. The crucial thing is to comprehend two concepts called filter context and row context. Each of the 72 results for the Sales measure has a distinct filter context. The implicit CALCULATE converts the row context into an equivalent filter context. Aug 21, 2018 The power in Power BI comes from the Dax language. DAX Formatter is a free tool by SQLBI that transform your raw DAX formulas into clean, beautiful and readable code. Now there is a row context AND and a filter context. DAX filter context is a stack of tables. Filter context: The filter context takes focusing on values one step ahead. Related articles. Mar 21, 2011 Marco Russo and Alberto Ferrari have introduced DAX filter context in Chapter 6 of their book Microsoft PowerPivot for Excel 2010. There are three types of context in a DAX formula – query context, filter context, and row context. If, however, multiple dimension members are in the filter context, the measure should compute the average of the latest values for these members. Row Context and Filter Context. A key to understanding DAX is to distinguish Filter Context and Row Context. I won't go into the  May 22, 2018 Yes you can create a measure returning a text string, such as the same value in all filter contexts within a particular report page (sounds like  Jun 24, 2017 Filter Context: can be simply defines as filter context the set of filters applied to the evaluation of a DAX expression, usually a measure,  Evaluates an expression in a context modified by filters. This provides another way to change the query context for any aggregation. The ALL function is being used to return a table to be used as the first parameter of the RANKX function. Power BI: DAX: Filter Functions The filter and value functions in Data Analysis Expressions (DAX) are some of the most complex and powerful, and differ greatly from Excel functions. This means, the results of a DAX formula can vary according to the The difference here is that CALCULATE allows simple filters which will replace the existing filter context. Understanding Measure Calculation. The Calculate function is capable of changing a row context into a filter context. ) CALCULATE in DAX is such a powerful and complex function to fully understand. The first is filter context and the second is row context. Filter Context: can be simply defines as filter context the set of filters applied to the evaluation of a DAX expression, usually a measure, regardless of how they have been generated. The external filter context is the combination of slicers and filters. This function is different from ALL() because it retains all filters explicitly set within the query, and it retains all context filters other than row and column filters. Given a pivot table, a filter context is initially populated by adding slicers and page filters. Move current rows in the row  Dec 19, 2012 CALCULATE is the single most important function in Data Analysis Expression ( DAX) because it allows you to manipulate filter context, which is  Jul 8, 2017 So automatically, something seemed off to me. DAX Measure calculates over a smaller column 2. The CALCULATE function in DAX measures; Removing filters in an expression using CALCULATE (this blog) Using the CALCULATE function to replace filters How do I create a DAX measure in Power Pivot that shows the column name that is used as the lowest level filter context for each row in the Pivot Table? I have 2 tables which are related on the Ac In the previous article of this series, Andy Brown of Wise Owl Training explained how to use the oh-so-important CALCULATE function in DAX to make changes to the default filter context within a formula. FILTER retains and iteracts with initial filter context, while filter expression used directly in CALCULATE ignores it. For more info about row and column context (and general DAX) you can watch this great webcast from Ashvini Sharma from the SSAS PM team : FILTER can filter rows from a table by using any expression valid in the row context. May 29, 2015 is the native query and formula language for Microsoft Power Pivot data Filter context is applied by utilizing a DAX functions such as FILTER,  Mar 10, 2014 The measures you want to segment have to evaluate only the rows with a . Measures are designed to return a single value, given the filter context that's applied to them. The Example Database for this Article. Filter context is added when you specify filter constraints on the set of values allowed in a column or table, by using arguments to a formula. Create a new filter context by cloning the existing one. dax measure filter context
