Calculation of sale same period last year when no sale in selected period.

I have the following simple model:



I need to be able to create a measure that calculates lost sales to customers in a given period, where lost sales are defined as:

Situation where a customer has no positive sales in the selected period, and where sales in the same period last year are positive.

I would like to be able to insert the measure with the DAX calculation into the matrix and display a lost sale per customer and total for the customers shown.

In the example shown, a lost sale of 100 for customer Cust.6 and Cust.8 and a total of 200 should be shown.

I have now been trying to make a calculation for a long time, and I therefore now want to ask if there is a quick expert here who can help me.
