In Messaging this concepts concept translates into a message that has the same effect whether it is received once or multiple times. That is, if the same message is presented to the system for processing more than once, subsequent occurrences will be treated as technical duplicates and discarded. A message is considered the same if a hash of that message creates an identical value to that of a previously received message. For an ISO 20022 message this includes the entire ISO 20022 Business Message, being both Business Application Header (BAH) and the Document part. |
