Caclulating a cusomter count - help!

[Livia_Hernandez]

I'm new to this code writing....  I'm trying to sum the number of unique customer codes that enter in our stores.  I am coming up with a total by location but the region totals do not sum the stores.  I'm at a loss...

Customer = DISTINCTCOUNT((CTMasterTemplate[GersCustomerCode]))  

The result is this:

When I add the stores independently it should equal the 1663.  Perhaps the same customer entered into a diff store?  I just want the numbers to add up.  I tried a couple different things with no luck.  😞

Hi @Livia_Hernandez ,

Try the following formula which gets the cumulative value correctly.

M1 = DISTINCTCOUNT('Table'[Customer])

M2 =
SUMX (
    VALUES ( 'Table'[Product] ),
    CALCULATE ( DISTINCTCOUNT ( 'Table'[Customer] ) )
)

Hi @gmsamborn -  I defintitely thought of that too.  I was just trying to see how I could other than manually make the summs just count the stores.  I tried group by with no luck.  Just checking if I was doing something wrong or missing some sort of logic.

 Thank you for replying!

Hi @Livia_Hernandez 

Is it possible that a customer can be related to more than 1 StoreCode? 

In a case like that, each StoreCode would count that customer but that customer would only be counted once in the total.
