Segment Notes: |
This segment is used to
envelope the interchange and also to identify the
party for whom the interchange is intended and
the party who has sent the interchange. The
principle of the UNB segment is the same as a
physical envelope which covers one or more
letters or documents and which details the
address where delivery is to take place and the
address from where the envelope has come.
DE 0001: The recommended (default) character set
for use in EANCOM for international exchanges is
character set A (UNOA). Should users wish to use
character sets other than A then agreement on
which set to use should be reached on a
bi-lateral basis before communications begin.
DE 0004 and 0010: Within EANCOM the use of the
EAN location number is recommended for the
identification of the interchange sender and
recipient.
DE 0008: The address for reverse routing is
provided by the interchange sender to inform the
interchange recipient of the address within the
senders system to which responding
interchanges must be sent. It is recommended that
EAN location numbers be used for this purpose.
DE 0014: The address for routing, which was
originally provided by the interchange recipient,
is used by the interchange sender to inform the
recipient of the address of the recipients
systems to which the interchange should be
routed. The address provided here is normally
informed to the interchange sender by the
recipient in advance of the interchange
transmission. It is recommended that EAN location
numbers be used for this purpose.
DE S004: The date and time specified in this
composite should be the date and time at which
the interchange sender prepared the interchange.
This date and time may not necessarily be the
same as the date and time of contained messages.
DE 0020: The interchange control reference number
is generated by the interchange sender and is
used to uniquely identify each interchange.
Should the interchange sender wish to re-use
interchange control reference numbers it is
recommended that each number be preserved for at
least a period of three months before being
re-used. In order to guarantee uniqueness the
interchange control reference number should
always be linked to the interchange senders
identification (DE 0004).
DE S005: The use of passwords must first be
agreed bi-laterally by the parties exchanging the
interchange.
DE 0026: This data element is used to identify
the application on the interchange recipients
system to which the interchange is directed. This
data element may only be used if the interchange
contains only one type of message, e.g. only
invoices. The reference used in this data element
is assigned by the interchange sender.
DE 0031: This data element is used to indicate
whether an acknowledgement to the interchange is
required or not. The EANCOM CONTRL message should
be used to provide acknowledgement of interchange
receipt. In addition the EANCOM CONTRL message
may be used to indicate when an interchange has
been rejected due to syntactical errors.
DE 0032: This data element is used to identify
any underlying agreements which control the
exchange of data. Within EANCOM the identity of
such agreements must start with the letters
EANCOM with the remaining characters
within the data element filled according to
bi-lateral agreements. |
