Georgia Blomberg, of EAN Australia, asked "What is the convention for
using the UN/EDIFACT INVOICE message with code '381'-Credit Note in the
BGM segment for message function? Are the monetary amounts therein
signed negatively or left as positive due to the message function
indicating this is a credit? Can anyone direct me to UN/EDIFACT or other
user documentation that can verify the correct approach?"
A credit note (or negative invoice) is used to indicate a refund to a
customer, and you'll see it done both ways - i.e., it's common enough to
have negative quantities and/or amounts specified.
On the other hand, EANCOM Part 1 section 2.2.6 - Representation of
numeric values - states:
Numeric data element values shall be regarded as positive.
Although conceptually a deduction is negative, it shall be
represented by a positive value, e.g. in a credit note all
values will be positive, the application software will using
the message name coded (DE 1001) convert all values into
negative. In addition some data element and code combinations
will lead to implied negative values, e.g. data element
5463 with code value 'A, Allowance' in an ALC segment in an
invoice.
Georgia, to be politically correct, might find it prudent to follow the
EAN guidelines.
