Calculated Column - Distinct Count By Another Column and Filter By Column

[Anonymous]

I have a table with 3 columns, Customer Number, Account Number & Flag. I want to create a calculated column(NOT A MEASURE) which counts the number of accounts per customer when the flag is set to yes.

CustomerNumber AccountNumber Flag ExpectedOutput Actual Output
1 A1 Y 1 3
1 A2 N 1 3
2 A3 Y 2 3
2 A4 Y 2 3

I am using the following formula

Total Business Investment Products =
CALCULATE (
DISTINCTCOUNTNOBLANK ( 'Fact'[AccountNumber] ),
FILTER ( 'Fact', 'Fact'[Flag] = "Y" ),
ALLEXCEPT ( 'Fact', 'Fact'[CustomerNumber] )
)

Hello @Anonymous  Give this a try

Total Business Investment Products =
CALCULATE (
    DISTINCTCOUNT ( 'Fact'[AccountNumber] ),
    ALLEXCEPT ( 'Fact', 'Fact'[CustomerNumber] ),
    'Fact'[Flag] = "Y"
)

@jdbuchanan71  This works but when I use it as Filter('Fact','Fact'[Flag])='Y') it doesnt work? Do you know why?

I believe the ALLEXCEPT is removing the fitler added in the FILTER statement.
