The goal is just understanding the theory. All rights are reserved. However, you can use the ALL function when filtering to work with the entire table, rather than just the data for the current filter context. 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. Clears filters from the specified tables or columns. Get the latest news and training with the monthly Redgate UpdateSign up, Creating Time-Intelligence Functions in DAX, // multiply the price of each transaction by, // calculate the total sales for the current filter context, // divide this by total sales for all cities, // create a variable to hold the sales in the USA, // create another variable to filter this to show, // finally, calculates sales for these figures, // ... the number of purchases is more than 1, Using the DAX Calculate and Values Functions, Cracking DAX – the EARLIER and RANKX Functions, Spreadsheet blamed for UK Covid-19 testing debacle, Introduction to DAX Financial Functions – Part 1. Even if you remove the filter from the Product[ProductKey], the filter on Product[Color] remains in place. Let us be more accurate and speak in terms of expanded tables: You can obtain a similar behavior by using the good old method of using the bridge table to move the filter from the many side to the one side, like in the following code: Why is this relevant, while speaking about filters? This will add a new table to your report to contain your measures. Le funzioni di filtro e per i valori in DAX sono tra le più complesse ed efficaci e sono molto diverse dalle funzioni di Excel. From SQL to DAX: Implementing NULLIF and COALESCE in DAX, Set functions in DAX: UNION, INTERSECT, and EXCEPT, Creating a simpler and chart-friendly Date table in Power BI, Creating calculation groups in Power BI Desktop using Tabular Editor. Displaying filter context in Power BI Tooltips Switch to the Home ribbon and select Enter Data. This set of Product[ProductKey] becomes a filter on Sales[ProductKey], and this filter is applied to the Sales table, resulting in the sales for only the given color. The answer is that within this formula, row context, not filter context, is used. Returns all the rows in a table, or all the values in a column, ignoring any filters that might have been applied. Otherwise returns alternateResult. 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. This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules. I think expressions using the FILTER function are easier to understand than equivalent expressions just using CALCULATE. The final report table shows the results when you create a PivotTable by using the measure, NON USA Internet Sales. I want to show a few examples that – at the beginning – act as mind traps. The filter and value functions in DAX are some of the most complex and powerful, and differ … Per creare questa misura occorre filtrare la tabella Internet Sales USD tramite Sales Territory e quindi usare la tabella filtrata in una funzione SUMX.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. C# training for businesses in the UK. Every example shown so far has taken the set of rows for the current filter context and applied additional constraints to pick out only certain rows. Returns TRUE if any of the arguments are TRUE, and returns FALSE if all arguments are FALSE. You can use FILTER to reduce the number of rows in the table that you are working with, and use only specific data in calculations. If you come from a previous programming or query language, you tend to map your previous knowledge to DAX, forgetting to follow the simpler path of using just the base rules of the language. The Sales, City and Country tables are related as follows: What’s needed is to iterate down the rows in the sales table, calculating the sales (price times quantity) for each but only where the country name is USA. I need to to do 3 mesaures that I am struggleing with. It just looks up the name of each city in which sales took place: Here’s the formula for the Sales year column. It returns a table of the filtered rows, and sometimes it is the better approach to take. You could use this, for example, to show the percentage contribution of each city’s sales to the grand total: Here’s the formula for the above measure: Incidentally, if you’re wondering how to get the nice percentage format, just select the measure you’ve created: You can then set the formatting in the Modeling tab on the menu: To see the difference between the way in which CALCULATE and FILTER filter data, consider this example: The first measure applies the filter context (so it only calculates sales for the city in question), and applies an additional constraint that the city should be New York: The second measure replaces the filter context with a new constraint that the city should be New York, which results in the same figure appearing in every row: To make debugging easier, first add a couple of calculated columns to the Sales table, to give the city name and sales year. This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules. The function can apply one or more search conditions. The reason is that this code removes the filter on Product[Color] because it removes any filter from any of the columns in the expanded version of Sales. In fact, if you define the measure as follows: The result is – again – the same value repeated for all the rows. To work through the examples in this article, you’ll need to create a simple Power BI report containing a single table and then create and show a series of measures. 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. Here are the figures that this should return: There are no sales recorded for Chicago, LA and Rio in the new measure because they each only witnessed a single sale. The inner FILTER function iterates over each row in the table of data for the filter context, picking out only rows where the country is in the USA. Per ricreare questa tabella, aggiungere il campo SalesTerritoryCountry all'area Etichette di riga di un report o di una tabella pivot.To re-create this table, add the field, SalesTerritoryCountry, to the Row Labels area of a report or PivotTable. It gives the year in which each sale took place: These two columns will make it easier to check what’s going on when debugging. Using CALCULATETABLE you propagate a filter to all the expressions embedded in the first argument. Here I’ve called mine All measures: Click Load. Removes context filters from columns and rows in the current query, while retaining all other context filters or explicit filters. There are two basic ways to do this in DAX – either by using && or the AND function (or if either of two conditions can be true, using || or the OR function). Removing the filter from the Account table or from the Transactions table, in this case, proves useless. The table to be filtered. In fact, every filter argument in CALCULATETABLE corresponds to an internal FILTER on a single column.
