On Wholesale - Sales, click the total checkouts with coupons tile to open the coupon list (Order, Code, Coupon, User, Checkout Total, Discount Total, Creation Date) limited to wholesale orders. The page's markup also contains user and subscription pop-up templates, but in the current version their data isn't even being loaded and no tile opens them – so the only detail pop-ups you can actually open on this report are Total sales (module breakdown) and the coupon list. For a per-order list of wholesale checkouts use the Taxes report (its Type column identifies each order's module) or the Customer Orders list.
