I need help understanding the impact of one DAX measure verus the other. I'm trying to do a distinct count of customers, but "Blank" values are also counted, so I want to exclude those with a filter.
Initially I was using this DAX code:
Customers (Count) := CALCULATE ( DISTINCTCOUNT ( Fact_Table[Customer Key] ), FILTER ( Fact_Table[Customer Key], ISBLANK ( Fact_Table[Customer Key] ) = FALSE ) )
But changed to this DAX code:
Customers (Count):= CALCULATE ( DISTINCTCOUNT ( Fact_Table[Customer Key] ), ISBLANK ( Fact_Table[Customer Key] ) = FALSE )
Using the FILTER was not performant at all when applying the measure to a table with thousands of records returned. What gives? How is the first query different than the second?
Thanks!
