Abandoned checkouts per affiliate

Two affiliates send you the same traffic and close a similar number of sales. One of them also leaves a pile of checkouts started and never finished, and the dashboard table showed you the sales but not the abandons.
The enemy is an abandon count you have to piece together by hand.
There is a new metric, Abandons. It counts abandoned checkouts: a shopper started an order and did not complete it. A checkout that is still inside the merchant's wait window, where the shopper may still come back and buy, is not counted. You can pick Abandons anywhere you choose metrics: reports, dashboard tables and KPI tiles. It is also a default column on the analytics dashboard's breakdown table, on the Affiliate and Sub ID tabs, right after Sales, so you see how many abandons each affiliate's traffic produces next to their sales. Adding it changes no other number.
Try it: open Analytics, scroll to Breakdown tables and stay on the Affiliate tab. Abandons is the column after Sales.
