Unique shops measure

[laba031095]

Hello. I have a table, for example:

Shop1 Product 1
Shop1 Product 2
Shop1 Product 3
Shop 2 Product 1
Shop 3 Product 1
Shop 3 Product 2
Shop 3 Product 3
Shop3 Product 4

What measure should I prescribe so that when choosing SKU, I can see only those customers who have sold all the selected SKU?

For Example

If i Select Product 1 Product 2 and Product 3

I see in table

Shop 1
Shop 3
Total: 2

If i select Product 1, i see

Shop 1
Shop 2
Shop 3

Total:3
