calculate a measure with a filter option and a filter option "not in"

[morizf]

Hello together,

i need help on a measure to calculate a quote. I have a table like this:

To get the quote i need the distinctcount article where the invoicetype is "nachorder". This is no problem

 CALCULATE(DISTINCTCOUNT(Article, invoicetype = "nachorder"). The problem is i need also the distinctcount where the invoicetype is "nachorder" and not "vororder"

CALCULATE(DISTINCTCOUNT(Article, invoicetype = "nachorder" && NOT(invoicetype = "vororder"))

but this doesn't work, can somebody help me with this measure?

Thank you in advance

Hi @morizf 

I suggest to create a calculated column to exclude values first:

IsValid Column = 
IF (
    CALCULATE (
        COUNTROWS(MyTable),
        ALLEXCEPT ( MyTable, MyTable[Article])
    )
        <> CALCULATE(COUNTROWS(MyTable), ALLEXCEPT(MyTable, MyTable[Article], MyTable[invoicetype])),
    FALSE(),
    IF (
        CALCULATE (
            VALUES ( MyTable[invoicetype] ),
            ALLEXCEPT ( MyTable, MyTable[Article], MyTable[invoicetype] )
        )
            <> "nachorder",
        FALSE(),
        TRUE ()
    )
)

And later on, count over this column:

Measure = CALCULATE(DISTINCTCOUNT(MyTable[Article]),MyTable[IsValid Column]=TRUE())
