There are two situations for cancellation of order.
If Customer only cancel one of or not more than the multiple items in one order, which is completed successfully afterwards, the items in the order will still be eligible to be reviewed for Customer to earn Merchant Points.
If the entire order has been cancelled, Customer will not be able to review it, thus unable to earn Merchant Points.
