DEFINITION

This field specifies the function of the message.

CODES

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

AMND	Amendment	Replaces a previously sent message with the amended one contained in this message. Used to add settlement agents to an MT 340 previously sent or to correct error(s) in an MT 340 previously sent.
CANC	Cancellation	Cancels a previously sent message. Used to cancel an MT 340 previously sent or to cancel an MT 340 which contains erroneous information.
NEWT	New Confirmation	Used to send the MT 340 for the first time or to send a corrected MT 340 when the erroneous one was cancelled using an MT 340 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. The cancellation function must not be used to terminate the FRA.

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