Subject: Re: [ubl] Approach to reporting scemantic errors on an invoice. Anyadvice?

I agree with Steve Capell - the requirement is not completely clear.

But if we were to assume that what you need is another UBL document type 
and not a messaging protocol signal then there is currently a proposal 
to introduce several additional document types for UBL 1.1 Billing process.

The European Government Agency's UBL collaboration group has had a long 
discussion about the value of an Invoice Response document type. They 
currently recommended not introducing this document because of the 
commercial complexities (and taxation issues) that may result. I guess 
it is not as simple as the Order-Order Response pattern.

Rather they recommend using a Debit Note sent from the Buyer to the 
Seller, stating that Buyer has deducted amounts from a Sellers Invoice. 
In situations
where a Buyer and Seller have agreed to the use of a Debit Note, a Debit 
Note obviates the need for the Seller to create a Credit Note.

My interpretation of this is that the Debit Note forms a kind of 
business-level negative acknowledgement. It is used to communicate 
variance between what was Invoiced and what the payee intends to pay. 
Its key advantage is that is a recognized VAT document.

However, I am only an observer of this debate so others may have more to 

The UBL 1.1 process model also introduces a Statement document type 
which could provide further reconciliation if necessary. For the 
complete model see the notes attached to...

The models for these new document types are being rationalized over the 
next few weeks so it would be useful to get you input into their 
suitability for your requirement.

Hope that helps.
