Question

Can Distinct Values be Counted in Power BI with a Filter?

 Distinct values can be counted in Power BI using the COUNTROWS or DISTINCTCOUNT functions, and applying a filter through CALCULATE to refine the count based on specific conditions.

Answer 1

Undoubtedly, it is possible to count distinct values in Power BI with a filter in place. Here’s how you can achieve it:

Employing the DISTINCTCOUNT function: In addition, Power BI contains the DISTINCTCOUNT function, which returns the count of distinct values in a particular column. In this case, one can combine this function with a filter to count the number of unique values that pass certain criteria.

Introduce a filter: There are various ways in which filters can be introduced. For instance, a user can utilize a slicer, visual level filters, or DAX such as CALCULATE to place a condition. DAX being applied, this could be the formula:

DistinctCountWithFilter = CALCULATE(DISTINCTCOUNT(Table[Column]), Table[Condition] = "Value") 

This calculates the number of different entries in a certain data frame column, but only for the entries that satisfy the filtering criteria (for example, when one of the data frame columns takes on particular values).

Visual Filters: If you are in a report, you can also use a visual filter on your table or chart, which will filter the information before the distinct count takes place.

This process helps Count Unique Values even while Filtering in Power BI.

Answer 2

Yes, filter distinct values in Power BI counting its distinct values using the function DISTINCTCOUNT. Then, use CALCULATE with a filter to narrow the counts based on other conditions: This is an example: END.

DistinctCountWithFilter = CALCULATE(DISTINCTCOUNT(Table[Column]), Table[Condition] = "SomeValue")

This counts the distinct values in Column where the condition is met.
