Year over Year sales variance when product sold in both years

I am analyzing margins for a list of products and there are obviously products that were sold last year that did not sell this year and vice versa. Has anyone ever built a report that only returns products that were sold in both years? I think this would give us better insight into pricing decisions we’re making (or should be making). Thank you

You can add that with advanced search for any number of time periods.

In the example from our database it dropped from 487 products examined to 281.

That’s fantastic. Thank you!
