If the Order was canceled and you want the customer to be able to use the Discount Coupon on another order, you would need to remove the record for its previous use in the table:
Once the coupon has been used on a previous order and it cannot be used again. The only way is to create another voucher for another order.
I explain better: my customer has made a purchase using the discount coupon. For various reasons we have to cancel this order (goods no longer available), but my customer wants to use the voucher on another order. How to solve it?
I do not want to delete the coupon, I just want to cancel the use of coupons for that customer.
