The Sales by Order report shows payment method but does not show where a customer has used their rewards points as a part payment.
This is a shortfall of the report if it is used for sales reporting as it overstates the revenue received.
It's fine if a voucher is used as this comes off the sales total prior to payment.
One has to run the transaction log and filter out any rewards points and deduct them from the totals making it a longer process.
