Using the New Table button in Power BI Desktop to materialise the table into the data model after data load as I covered here. Selected Values doesn’t check to see if the column has an active filter on it, instead it’s only checking to see if there’s a single value from that column. I'm using this to clear any filters applied to the Category field in the 'Demo Data' table. You can set up a measure that returns a boolean, date A key to understanding DAX is to distinguish Filter Context and 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. Using filtered data as a replacement for a full table. Want to learn more about using DAX and Power BI? 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. This DAX expression checks if the user applied a filter on the Store/Territory column, such as by using a slicer, and generates the filter URL using the available values if this is the case. In some cases we want to do grouping based on the values of a column. With multi-dimensional cubes and MDX you can create calculated members in a dimension. And FILTER doesn’t take multiple arguments the way CALCULATE does, so we use the && to combine our conditions. Time to correct that. We are using a measure here since a particular region can have any number of rows involved within it.

To create this measure, you filter the table, Internet Sales USD, by using Sales Territory, and then use the filtered table in a SUMX function. This means that each time we create a measure, it goes back and uses the source data rather than creating a measured calculation against measures already in the pivot table. 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. The thing both of those formulas have in common is that they are using a measure in the filter argument of the CALCULATE function.

This is useful whenever you have custom calendars, such as an ISO 8601 week calendar, or when you are using an Analysis Services Tabular model in DirectQuery mode. Thus, the ClusteredSales measure that computes the value using the selected clusters has to use a more complex FILTER function inside the CALCULATE function: for each customer, it has to evaluate the sum of SalesAmount applying existing filters and slicers, but removing all the filters defined in rows and columns. i've created a virtual table but have discovered that there is no row context within the virtual table. Quite recently a colleague asked how you could calculate this in DAX.

Background:Before we jump right into it, let’s outline the data In my last post, I explained how to create a Calculated Column that aggregates values in the Power Pivot data set for rows that meet specific filter criteria (by using the CALCULATE, SUMX, and ALLEXCEPT functions, you can customize exactly which rows you want to have included in your sums for a column). I managed to solve this by using the following DAX: New measure = CALCULATE( [measure_name], FILTER(Table_name, Table_name[field_name]="Value A (or Value B)") ) The SELECTEDVALUE DAX function seems to give the same result as well. In this article, we will learn some basics of querying a SSAS Tabular model database with simple DAX queries, starting with a theoretical approach, and then retrieve data and analyze it. … ) We call FILTER() ‘cuz we want to filter the properties… and because we are using MAX() we cross that magic threshold into “too complicated an expression, must use FILTER”. The measure is then in essence ‘disconnected’ to the table, but it will provide us with a value for our TopN slicer. All good points – we know we have to review all of the DAX patterns using the new features in DAX, and VAR is probably the most important one! Be patient, now that we completed other things… this is very high in priority list! Thank you for reminding me that we have still article out there using the legacy EARLIER stuff!

There are some certain key issues that we’ve got to work through though, and we’ll do that using a conditional DAX measure. for exmample; Measures='ab' calculate (sum(x),filter(y,column='ab') is not the same as calculate (sum(x),filter(y,column=Measures) do you know why? FILTER is not used independently, but as a function that is embedded in other functions that require a table as an argument. This is probably the hardest concept to understand when using DAX. Using a date table, you can create a DAX measure that can then be used as a Power BI report-level filter to dynamically filter by today’s date within Power BI Desktop. I have previously written about using Power Query for creating calendar tables, However, some people still love to do that in DAX. The easiest way to think about it is to actually walk through an example. Every row in column G is going to show the total for all sectors, even though the row label in D5 says that this row is for Appliance. The DAX time patterns are used to implement time-related calculations without relying on DAX time intelligence functions. Simple linear regression pattern. The filter context is one of the two contexts that exist in DAX. Principle - Duration: 5:23. The use case is simple: there are employees that perform hours on specific tasks. Whenever you start trying to use more complicated filters in the CALCULATE or CALCULATETABLE functions in DAX, you may start to get the following error:. However, in PowerPivot a Measure uses DAX functions. 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. filter using a measure dax
