Intersections of customer product purchases

[Anonymous]

Hi

I need help with producing a count of the intersections bewteen customers and which items they have purchased. For example, if there are 5 products, a customer can purchase any single product or any combination of the 5. Customers can also re-purchase a product at any date - this is where my problem arises as an end user wants to be able to see the intersections for any selected date range.

I have managed to come up with a solution which includes the use of parameters but this is not ideal as the end user does not have access to change any parameters of the report.

I'm open to any solution that does not involve parameters, ideally a slicer with dates would be the best solution

The fields I have on the table are customer_ID, date_ID and product

Example Data

Possible output with different slicer selections

This is my first post so please don't hesitate to ask if I need to provide any more information that would help with a solution

Any help at all would be greatly appreciated

Hi,

AFAIK, current power bi not support to use slicer/filter to create dynamic calculated column/table. (Measure is possible to achieve this, but it not support to use as category)

So I think it is impossible to dynamic generate output table based on selection.

Sample measures:

Product List =
CALCULATE (
    CONCATENATEX ( VALUES ( Table1[product] ), [product], "," ),
    VALUES ( Table1[customer_id] )
)


Product/Custom Detail = 
VAR temp =
    SUMMARIZE (
        ALLSELECTED ( Table1 ),
        [customer_id],
        "Product Combo", CONCATENATEX ( VALUES ( Table1[product] ), [product], "," )
    )
VAR t2 =
    SUMMARIZE (
        temp,
        [Product Combo],
        "Customer list", CONCATENATEX (
            FILTER ( temp, [Product Combo] = EARLIER ( [Product Combo] ) ),
            [customer_id],
            ","
        )
    )
RETURN
    CONCATENATEX ( t2, [Product Combo] & ":" & [Customer list], "|" )
