It is recommended to implement the EDIFACT FINPAY message with the segments of the currently accepted EDIFACT directory. Any deviation should be governed by a bilateral agreement between the Sender and the Receiver.
This message cannot be used for EDIFACT FINPAY messages exceeding the maximum length specified above. Longer EDIFACT FINPAY messages can, however, be sent using multiple MT 106s.
Retrieval of this message will be possible according to all normal criteria except field 20 Transaction Reference Number.
Control of delivery of this message will be possible according to all normal criteria. When control of delivery is based on the message category, this message will be grouped with the other Category 1 messages.
In common group messages, the MT 121 can only be described using a narrative description because this message contains no tagged mandatory field and the common group messages do not support the 'y' character set. Wherever, field 21 Related Reference is mandatory in the common group message, it is recommended to use the text 'EDIFACT FINPAY' because the MT 121 does not contain a field 20 Transaction Reference Number and the common group messages do not support the 'y' character set.
