Report: Report that shows what customers have not yet bought a given product
We are looking for a report that will identify those customers who have not bought a given product.
For example, if I have products A, B, C, and D. And I have customers X, Y, and Z. If customer X has bought products A and B, but not C and D from me, I would like the report to highlight this for me.
Alternatively, the report could have the quantity purchased for all products (regardless of whether it has been purchased or not) for a given customer, and those products that have a zero quantity would be the products not purchased by customers.
This could be time range like other reports so that you can see specific time ranges when products were not purchased by customers.
