Subject: Re: [ubl] How does an OrderResponse show order acceptance/rejection?

mm1: A simple yet relevant example is a good premise.  This should work 
fine with ebBP and the team can provide guidance and assistance as 
required. There are other aspects to consider, which touches on our 
previous discussion of a logical business document and what is being 
specified here.

mm1: Inherent in the business process, the shared expectation between 
the parties (i.e. Buyer Party and Seller Party) would be whether or not 
a response was Order Response or Order Response Simple.

mm1: The UML models I have seen indicate that a Reject Order is 
possible. What is the limitation? Typically an Order Response could be 
complete or partial fulfillment of an order, or can't fulfill.

>Simple the Seller cannot (using UBL) propose modifications to the Order. 
mm1: See above. As long as we understand the limitation we can work to 
sufficiently model it in the business process. Whether or not changes 
are considered because of this in UBL is this team's department.

>They would have to do this using another form of document (eg paper or 
>fax) or even ring up.  The business process model needs to show this 
>(ie. revert to manual process).  
mm1: There are two separate aspects of this - the identification of 
functionality that may not be currently provided in UBL (whether v1.0 or 
v2.0) and then allowing this to be handled in the process model.  For 
example, the ebBP Specification element in complement with expressions 
(condition constraints and semantic variables), provide a hint whereby 
the decision is raised to a person (we added these changes because of 
earlier UBL inputs).

>in terms of UBL documents.  I think the ebBP description should handle this.
mm1: See above.

>When it comes to what to do with UBL 2.0 we could review this process.

mm1: This is indicative of the logical business document approach where 
it can serve many purposes. Only side comment is that the 
Acknowledgement and the business validation (Acceptance) signals are 
separate from the Order Response document itself. I understand this may 
not be exposed in UBL; however, it may be a point of confusion. The 
actual business document is the substantive response to an offer; the 
signals provide state alignment checks and balances to ensure the 
parties expectations are being met and the process is proceeding 
(regardless of what the outcome is).
