#SUMMARIZE DAX HOW TO#

Discounted price = sumx(cars cars-10000)įirst argument declares that we want to work with 'cars' table.

Theoretically, we could create a new column with difference, and then summarize it.

#SUMMARIZE DAX HOW TO#

But how to summarize the price, if every car was discounted by 10 000? To summarize the total price of all cars, we could use SUM simply. Let´s play with this table containing a list of cars and demonstrate three basic tasks, that can be nicely handled using SUMX. This article is about SUMX, but other 'X-function' such as COUNTAX, COUNTX, AVERAGEX, MINX, MAXX work similarly. It is very handful when we need to make some calculation 'before' summary or calculate selected rows only.

This article is about SUMX, which can be used in DAX. ISSUBTOTAL can only be used within a SUMMARIZE expression.SUMX – summary with filter or additional calculation (DAX – Power Pivot, Power BI) With ISSUBTOTAL, you can create another column in the SUMMARIZE expression that returns True if the row contains subtotal values for the column given as argument to ISSUBTOTAL, otherwise returns False. , ROLLUP(ROLLUPGROUP( DateTime, ProductCategory)) The following example shows only the grand total of all years and categories without the subtotal of each year with all categories: SUMMARIZE(ResellerSales_USD ROLLUPGROUP can only be used within a ROLLUP, ROLLUPADDISSUBTOTAL, or ROLLUPISSUBTOTAL expression. The addition of ROLLUPGROUP inside a ROLLUP syntax can be used to prevent partial subtotals in rollup rows. The following example adds rollup rows to the Group-By columns of the SUMMARIZE function call: SUMMARIZE(ResellerSales_USD ROLLUP can only be used within a SUMMARIZE expression. The addition of the ROLLUP syntax modifies the behavior of the SUMMARIZE function by adding rollup rows to the result on the groupBy_columnName columns. The following table shows a preview of the data as it would be received by any function expecting to receive a table: DateTime , 'Discount Amount (USD)', SUM(ResellerSales_USD) , 'Sales Amount (USD)', SUM(ResellerSales_USD) The following example returns a summary of the reseller sales grouped around the calendar year and the product category name, this result table allows you to do analysis over the reseller sales by year and product category. This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules. The function groups a selected set of rows into a set of summary rows by the values of one or more groupBy_columnName columns. GroupBy_columnName must be either in table or in a related table to table.Įach name must be enclosed in double quotation marks. The second argument, expression, defines the calculation performed to obtain the value for each row in that column. The first argument, name, defines the name of the column in the results. RemarksĮach column for which you define a name must have a corresponding expression otherwise, an error is returned. The name given to a total or summarize column, enclosed in double quotes.Īny DAX expression that returns a single scalar value, where the expression is to be evaluated multiple times (for each row/context).Ī table with the selected columns for the groupBy_columnName arguments and the summarized columns designed by the name arguments. (Optional) The qualified name of an existing column used to create summary groups based on the values found in it. Syntax SUMMARIZE (, ……)Īny DAX expression that returns a table of data. Returns a summary table for the requested totals over a set of groups.
