these messages constitutes a file. The File Name data element in the message indicates
the name of the file to be updated
at the receiver’s location. The Data Record data
element
in each one of these messages contains data from a number of business
transactions. The data contained in the Data Record data element may, or may not be
based on the message types identified
in this standard. The structure of this data
element
is left to the parties involved in the exchange. A file transfer is initiated with a
network message set (804/814), followed by a series of file action (340)
messages and
ended with another network message, as illustrated
in Exhibit 4.1-6.

Batch transfer allows transaction details to be sent as a series of notification, or
instruction messages with an optional reconciliation transaction. The Batch Transfer
does not require a response message for every message sent. Control is maintained by
the use of notification, or instruction acknowledgement messages, which may be sent
periodically within the transmission of a batch. There are no specific message types
needed to support the Batch Transfer. It is achieved
by the use of the existing message
types provided
by the standard.
The batch transfer is initiated by an 804/814 network management messages that define
transfer related control data such as number of messages contained in the batch. In the
example flow illustrated in Exhibit 4.1-7, a series of Financial Presentment Notification
Messages (240) are used in the batch transfer.
