Re: [ubl-dev] Why is a CreditNoteLine LineExtensionAmount optional

[Stephen D Green <stephengreenubl@gmail.com>]

A credit note does not always have lines because not all credit notes relate to invoice lines.

There is a normal business practice with paper credit notes to send a note with just the totals and literally a ânoteâ to explain it. Often this happens if an invoice is paid twice (such as once on a copy if the invoice is lost then again on the invoice if it turns up and nobody noticed it was already paid on the copy) or an invoice is paid to the wrong supplier. In the latter case there might be no record of the invoice by that wrong supplier, nor even a record of the incorrect payment. Simply it is easier to provide a nondescript credit note rather than refund if a lot of payments are regularly made (or wishfull thinking that the credit might never get taken if payments are rare).

UBL had a major design decision to be a replacement of paper documents which keeps to the normal paper document practices and structures and semantics.

An InvoiceLine LineExtensionAmount is mandatory, although the value can be zero, but for a CreditNoteLine it is optional. Why, and what would it mean to have a CreditNoteLine without a LineExtensionAmount?
