DEFINITION

This field specifies the function of the message.

CODES

Function must contain one of the following codes (Error code(s): T36):

AMND	Replaces a previously sent message with the amended one contained in this message. Used to add settlement agents to an MT 306 previously sent -or- to correct error(s) in an MT 306 previously sent.
CANC	Cancels a previously sent message. Used to cancel an MT 306 previously sent -or- to cancel an MT 306 which contains erroneous information.
NEWT	New confirmation. Used to send the MT 306 for the first time -or- to send a corrected MT 306 when the erroneous one was cancelled using an MT 306 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 the full details of the original transaction.

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