DAX formula Distinct/Distinctcount

Dear all,

I need to calculate the total number of customers for "Estimated Sales = SALES+FIRM ORDERS+FORECAST".  I applied a formulas DAX to calculate the sum of customers of the 3 categories below, however, the output is not the distinct number of customers for the total Estimated Sales. There are duplicates.  May you please help? Thanks.

NB Customers TO+FO+Frcst =
CALCULATE(
DISTINCTCOUNT(SALES[Customer_Code])
+DISTINCTCOUNT(SALES_FIRM_ORDERS[Customer_Code])
+DISTINCTCOUNT(SALES_FORECAST[Customer_Code])
)

 

SALES FIRM ORDERS FORECAST
Customer Code Customer Code Customer Code
A A B
B B C
C E F
D F G
E G H
A B C
C F

    Hey EZV12 ,

     

    you have to combine the columns first and then count the distinct values.

    Try the following measure:

     

    Amount Distinct Customers = 
COUNTROWS (
    DISTINCT (
        UNION (
            VALUES ( 'FIRM ORDERS'[Customer Code] ),
            VALUES ( FORECAST[Customer Code] ),
            VALUES ( SALES[Customer Code] )
        )
    )
)

     

     

    If you need any help please let me know.

    Try:

    Disctinct values =
VAR _Sales =
    VALUES ( 'Table'[SALES] )
VAR _FirmOrders =
    VALUES ( 'Table'[FIRM ORDERS] )
VAR _Forecast =
    VALUES ( 'Table'[FORECAST] )
RETURN
    COUNTROWS ( DISTINCT ( UNION ( _Sales, UNION ( _FirmOrders, _Forecast ) ) ) )
