Alternative to this DAX Expression? Count of unique combination of two columns

Helllo,

 

Anyone have a good suggestion for an alternative to this expression?

 

Unique CustomersProducts  = COUNTROWS(GROUPBY(fact_distribution;fact_distribution[fk_dim_customer];fact_distribution[fk_dim_publication]))
I tried with:
 
Unike CustomersProducts  =
COUNTROWS (
ALL (
fact_distribution[fk_dim_customer];
fact_distribution[fk_dim_publication]
))
 
This gives a much better performance, but because of the ALL it doesn't care about the filter context. The group by seems very heavy tho so it's a slow DAX expression.
 
Appreciate any help!

Best,
 
Ali A

@Anonymous The best way to approach this is to share sample data with what you are trying to achieve, it will help to get the proper solution.

Hi @parry2k ,

 

Ended up creating  a column in the DWH concatenating the fields and using a simple

CountRows(Distinct(ColumnName))

Worked wonders for the front-end part 🙂

 

Thanks for responding!

 

Best,
