get counts based on nested conditions

[Anonymous]

Hi 

I have following table

Product	Customer number
A	1
B	1
C	1
F	2
A	2

Definition of customer: If the customer has purchased product A or B, only then we consider the customer. 

I want to create a count of customers based on these criteria. Also, it needs to add slicer products. However, whenever I select product F, technically it should show 1 customer. But it is showing blank.

Thank you @ryan_mayu 

Hi, @Anonymous 

Based on the data you provided and the expected results described, I created a measure using the following DAX expression:

Count Customer =
VAR _seleted_product =
    SELECTCOLUMNS ( 'Table', 'Table'[Product] )
VAR _table =
    FILTER ( 'Table', 'Table'[Product] IN _seleted_product )
VAR _ID_AB =
    SUMMARIZE (
        FILTER ( ALL ( 'Table' ), 'Table'[Product] IN { "A", "B" } ),
        'Table'[Customer number]
    )
RETURN
    IF (
        ISFILTERED ( 'Table'[Product] ),
        COUNTROWS ( FILTER ( _table, 'Table'[Customer number] IN _ID_AB ) )
    )

Here are the results:

This is good. However, if I select A, B and F, it should return 2 as there are only two unique customer

Hi, @Anonymous 

Thank you very much for your reply. Using the following DAX expression will get a count of different IDs:

Count Customer =
VAR _seleted_product =
    SELECTCOLUMNS ( 'Table', 'Table'[Product] )
VAR _table =
    FILTER ( 'Table', 'Table'[Product] IN _seleted_product )
VAR _ID_AB =
    SUMMARIZE (
        FILTER ( ALL ( 'Table' ), 'Table'[Product] IN { "A", "B" } ),
        'Table'[Customer number]
    )
RETURN
    IF (
        ISFILTERED ( 'Table'[Product] ),
        COUNTAX (
            SUMMARIZE (
                FILTER ( _table, 'Table'[Customer number] IN _ID_AB ),
                'Table'[Customer number]
            ),
            'Table'[Customer number]
        )
    )

maybe you can try to create a new column

count =

VAR _A=maxx(FILTER('Table','Table'[Customer number]=EARLIER('Table'[Customer number])&&'Table'[Product]="A"),'Table'[Product])

VAR _B=maxx(FILTER('Table','Table'[Customer number]=EARLIER('Table'[Customer number])&&'Table'[Product]="B"),'Table'[Product])

RETURN IF(_A<>""&&_B<>"",1,0)

then you just need to sum the count column
