If a column contains a list of values

[KabirDhupelia]

I'm trying to track bundles of products through a set to see how many customers have a specific set of products.

The data structure is as follows:

Customer	Product
Customer 1	iPhone
Customer 1	iPad
Customer 1	AirPods
Customer 2	iPhone
Customer 2	iPad
Customer 3	Airpods
Customer 4	Airpods
Customer 4	iPhone

Could I write a DAX measure to determine how many distinct customers have the combination of at least an iPhone and AirPods?

Hi  @KabirDhupelia ,

I created a sample pbix file(see attachment) for you, please check whether that is what you want.

1. Create a product dimension table

2. Create a measure as below to judge which customer fulfill the conditions

Flag = 
VAR _selproducts =
    ALLSELECTED ( 'Products'[Product] )
VAR _selcustomer =
    SELECTEDVALUE ( 'Table'[Customer] )
VAR _selcount =
    COUNTROWS ( _selproducts )
VAR _custcount =
    CALCULATE (
        DISTINCTCOUNT ( 'Table'[Product] ),
        FILTER (
            'Table',
            'Table'[Customer] = _selcustomer
                && 'Table'[Product] IN _selproducts
        )
    )
RETURN
    IF ( _custcount >= _selcount, 1, 0 )

3. Create a table visual and apply the filter with the condition (Flag is 1)

If the above one can't help you get the desired result, please provide more sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

I guess you already have something as Product ID or you can generate 

Step1

Count_Like = CALCULATE(DISTINCTCOUNT(Like[Customer]),FILTER(ALLEXCEPT(Like,Like[Customer]), OR(MIN(Like[Product])="AirPods",MAX(Like[Product])="iPhone")))

Step2

Solution_Like = if( SUMX(ALLEXCEPT(Like,Like[Customer]),[Count_Like]) >= 2,1,0)

NOTE: Filter=1

Thanks! How would I do this if the bundle contained more than 2 products? 

[ribisht17]

I can give a code to the Product IDs

Count_Like_2 = IF(CALCULATE(SUM(Like[Produt ID]),FILTER(ALLEXCEPT(Like,Like[Customer]),Like[Produt ID] IN {3,1}))=4,1,0)

and will get the answer

You can add as many as products, it should give a unique value, in this case I need 4(1+3)

Thanks,

Ritesh
