NEWT	New confirmation. Used to send the MT 320 for the first time -or- to send a corrected MT 320 when the erroneous one was cancelled using an MT 320 with function CANC.

USAGE RULES

As the amend message replaces the previously sent confirmation, it must contain both the amended fields and the fields which are not changed.

When the cancel function is used, the message must reconfirm at least the mandatory fields of the original transaction.

Please refer to further guidelines under field 22B, Type of Event.

An amendment or cancellation always refers to the previous confirmation identified in field 21 of this message.
