DISTINCTCOUNT Function (DAX)

 

The DISTINCTCOUNT function counts the number of different cells in a column of numbers.

DISTINCTCOUNT(<column>)  

Parameters

column
The column that contains the numbers to be counted

The number of distinct values in column.

The only argument allowed to this function is a column. You can use columns containing any type of data. When the function finds no rows to count, it returns a BLANK, otherwise it returns the count of distinct values.

The following example shows how to count the number of distinct sales orders in the column ResellerSales_USD[SalesOrderNumber].

=DISTINCTCOUNT(ResellerSales_USD[SalesOrderNumber])  

Using the above measure in a table with calendar year in the side and product category on top gives the following results:

In the above example the user should be able to note that the rows Grand Total numbers do not add up, this happens because the same order might contain line items, in the same order, from different product categories.
