DAX to show the Customer_TK in a matrix with lost customer formula

I have used been using some DAX code for new and returning customers from sqlbi, though I am looking for a way to change/update the code to be able to show the Customer_TK in a matrix for Lost Customers.

Three other retention measures working, and when drill down to Customer_TK...

Working correctly.  Now I add the Lost Customer measure....

This works great with the date, but....

Not when trying to see the breakdown with Customer_TK

 

How can I modify this DAX to allow the Lost Customer measure to be filtered by the customer dimension in this matrix.

Here is the DAX...

 

 

Lost Customers = 

VAR LastDateLost = 
    CALCULATE(
        MAX(dim_date[date]),
        ALLSELECTED(dim_date)
    )

VAR CustomersWithLostDate = 
    CALCULATETABLE(
        ADDCOLUMNS(
            VALUES(fact[CUSTOMER_TK]),
            "@LostCustomerDate", [Date Lost Customer]
        ),
        ALLSELECTED(dim_customer),
        dim_date[date] <= LastDateLost
    )

VAR LostCustomers = 
    FILTER(
        CustomersWithLostDate,
        [@LostCustomerDate]
            IN VALUES(dim_date[date])
    )

VAR Result = 
    COUNTROWS(LostCustomers)

RETURN
    Result

 

 

Cheers

I will check out the video now.  I think your link might be wrong though.  I believe this would be the link you meant... https://www.youtube.com/watch?v=EyL7KMw877Q
