I would like to create a short table showing how much customers have bought how much product,s and I'm struggling getting the COUNT or COUNTROWS working as an expression within CALCULATE/CALCULATETABLE.
Here my table :
And would like to get:
Nbr of Products Nbr of Customers
1 3
2 2
How do I do that with DAX?
Thanks
Solved! Go to Solution.
Hi @clo_64,
I think I got to a solution:
Here the DAX:
New Table = VAR _helpTable = SUMMARIZE ( TableCustomerProduct, TableCustomerProduct[Customer], "Nbr of Products", DISTINCTCOUNT ( TableCustomerProduct[Product] ) ) RETURN SUMMARIZE ( _helpTable, [Nbr of Products], "Nbr of Customers", CALCULATE ( DISTINCTCOUNT ( 'TableCustomerProduct'[Customer] ), FILTER ( VALUES ( 'TableCustomerProduct'[Customer] ), CALCULATE ( DISTINCTCOUNT ( TableCustomerProduct[Product] ) ) = [Nbr of Products] ) ) )
The _helpTable does a grouping on customer with a distinct count on product. The return statement uses the Number of Products from the _helptable combined with a "having clause" in order to retrieve the number of customers per number of products
Let me know if this helps 🙂

Excellent! Very smart this double SUMMARIZE!
Thanks Tom
Hi,
Coulld you explain why you have 2 2 on the second line of your output? Shouldn't it be 2 1, as only the customer Gamma has bought 2 products?
Best regards.
Because Ypsilon has also bought 2 distint products.
