Content (please ensure you mask any confidential information):

if the delivery channel selected for a payment does not correspond to underlying supplier contact info available then the payment file fails and then has to be processed manually. The delivery channel is used to send the payment remittance to the supplier. The options used by the Finance Team are: Email, Fax and (blank). Therefore if Email is selected, then a valid email address must exist in the supplier contact details. Similar for Fax. For blank, then no additional contact details are required as no remittance will be sent to the supplier upon payment.
