Mandatory
This field contains the EDIFACT FINPAY message.
The contents of this field will not be validated except for the use of the 'y' character set, ie, EDIFACT level A/ISO 9735.
The effective maximum length of this field in a real message depends on the length of the added SWIFT headers and trailers. The field length will not be validated separately but only via the implementation rule defining the maximum length of the complete message.
