Find Customers who did NOT puchase X product(s)

[bkwohls]

As a FNG to PBI:

I have used the DAX formula below successfully to determine customers who have NOT purchased a specific product. What I NEED to do is correct this DAX to allow for the selection of multiple products. When multiple values are selected in my slicer I get an error

For Context

'Sales 4y' is my Sales Table

'Part DNS' is my list of Parts that I want to use as my DID NOT SELL list for use in a slicer

DID NOT SELL =

CALCULATE ( [Total Sales], FILTER ( 'Sales 4y', NOT ( CONTAINS ( 'Sales 4y', 'Sales 4y'[PartNum], VALUES ( 'Part DNS'[PartNum] ) ) ) )

The end visual is a Simple Table that shows the Total Sales for the Customers who did not purchase the selected items. Customer Name is in the Sales 4Y table.

Hi @bkwohls 

I don't follow completely but based on your current measure, try this:

DID NOT SELL =
VAR slicerVals_ =
    VALUES ( 'Part DNS'[PartNum] )
RETURN
    CALCULATE (
        [Total Sales],
        FILTER ( 'Sales 4y', NOT 'Sales 4y'[PartNum] IN slicerVals_ )
    )

 You might need an ALL('Sales 4y') as based for the filter or something else depending on how/where you use the measure

This works to display the sales for a customer that are not in the Did Not Sell list, However I want the [Total Sales] for the customers that never sold the part.

@bkwohls 

DID NOT SELL =
VAR slicerVals_ =
    VALUES ( 'Part DNS'[PartNum] )
VAR customerList_ =
    EXCEPT (
        DISTINCT ( 'Sales 4y'[CustomerID] ),
        CALCULATETABLE (
            DISTINCT ( 'Sales 4y'[CustomerID] ),
            FILTER ( 'Sales 4y', 'Sales 4y'[PartNum] IN slicerVals_ )
        )
    )
RETURN
    CALCULATE ( [Total Sales], customerList_ )

@bkwohls , Not very clear. But you use this meausre with customer and product if will give product not purcahsed by customer. You can use slicer filter too

not sold measure =

if(isblank( [Total Sales]),1,blaknk())

[bkwohls]

In 'Sales 4Y' Table I have fields Partnum,Customer, Sales $,Date. In 'Part DNS' table it is just a list of part numbers with no relation to Sales table. I want to use 'Part DNS' table as a slicer for user to select the part(s) to find customer who did not sell them. Is that more clear? How can I make more clear?
