A simple change that allows us to start measuring the percentage of orders with errors due to wrong addresses is including a Cancellation Reason attribute to the event. For example:
...
Solution Hypothesis
Using the cancellation reason as reduce delivery errors KPI will provide us with meaningful results as long as the following assumptions are true:
Delivery Partner operators correctly identify wrong addresses scenarios, and close the order with issues using the correct status
Deliver Partner System is sending the correct value for wrong addresses, as defined in Partner's API documentation (At least BK ES and BK PT are guaranteed to send it).

The existing name attribute of the event is an interpolation of the old and new status (${OLD_STATUS}-${NEW_STATUS}), therefore we can create a segment to measure the total number of orders with errors and compare the percentage of them caused by wrong delivery addresses. These are the metrics that can be used:
