DAX SQL window function equivalent

Hello,

 

I would like to create a calculated column that returns a total row count per customer, as below.

To do this with SQL, one approach would be to use a window function like:

 

COUNT(*) OVER (PARTITION BY CUSTOMER ORDER BY NULL)

 

Could someone please demonstrate how to achieve the same result using DAX?

 

Thanks!

Check

 

Column =
COUNTAX (
    FILTER ( 'Table', EARLIER ( 'Table'[Customer No.] ) = 'Table'[Customer No.] ),
    'Table'[Product Purchased]
)

What if we have unsorted list of Customer No.? They this formula shouldn't work, yes?

Lovely, thanks very much.
