EDI AUTHOR Authorization message

An Authorization Message is sent by the Ordering Customer (or Payor or Agent on behalf of the Ordering Customer) or by a third party having authority on the Ordering Customer's payments to the Ordered Bank, to authorize the Ordered Bank to execute a given financial transaction. This financial transaction might relate to both multiple messages like PAYMUL and DIRDEB, and single instruction messages like PAYORD and PAYEXT. An Authorization Message could also be sent from the Ordered Bank to the Ordering Customer or its Authorization Authority to request authorization for a given financial transaction. Throughout this document the term 'Original Message' refers to the message to be authorized.
