Subject: Re: PIP IDs


Thanks for the clarification.  As you are probably aware, there are other
response routing issues that have surfaced lately to the CPPA team, so this
topic will be on the CPPA agenda as well.  This is an area where the MSG
and CPPA teams will have to work together.

I have been assuming that for RosettaNet, a conversation equals one
execution of one PIP.  I believe that your note says that a single unit of
business in RosettaNet can involve several PIPs. What is your view of the
relationship of a PIP to a coversation.  Is each PIP a separate
conversation or should execution of all the related PIPs in a unit of
business be treated as a single conversation? Since the conversation
boundaries are determined by the application, this is really your call for
RosettaNet but I am interested in your thinking.

Subject:  Re: PIP IDs


Up to now, RosettaNet PIPs are either  request-response (two-actions) or
notification (one-action) style business  processes. Earlier versions of
PIP 3A4 are an exception in the sense  that PIP 3A4 covers Create Purchase
Order (request-response), Change  Purchase Order (request-response) and
Cancel Purchase Order (request-response)  interactions. Recently, PIP 3A4
has been split into 3A4 (Create Purchase Order),  3A8 (Change Purchase
Order), and 3A9 (Cancel Purchase Order) in order to achieve  some degree of
uniformity across PIPs (I believe). Therefore, I think it is  reasonable to
equate existing RosettaNet PIPs with BPSS Business  Transactions.

In the RosettaNet message header, there are  separate elements to identify
the PIP ID, the PIP action and the Service.  Multiple PIPs may be
implemented by the same service, e.g., there may be a Buyer  service
implementing PIPs 3A4, 3A8, 3A9 from the buyer perspective, and a Seller
service implementing the same PIPs from the seller perspective.

I don't think we should equate PIP ID with Service  and action with "the
particular business transaction within the PIP". Otherwise,  we will not be
able to capture the role information, e.g., the ability to  distinguish a
Buyer Service from a Seller Service, and a request action from a  response

From the RosettaNet point of view, it will be  desirable if we can have
distinct Service, PIP (equivalently BPSS Business  Transaction), and action
elements in the message header. Alternatively, we can  use the Service
element to capture role information (e.g., Buyer vs Seller), and  use the
Action element to capture the PIP ID. Whether we are dealing with a
request action or a response action will have to be inferred from the
Service  element.

In my opinion it makes more sense for Service to point to the PIP ID  and
action to point to the particular business transaction within the PIP.  In
other words one execution of a PIP is a conversation.  I believe that  some
of the PIPs include multiple business  transactions.

Subject:  PIP IDs

David, in the F2F you  mentioned the need for a new element to contain
industry specific business  process identifiers such as a RosettaNet PIP
identifier. Could this be done  with Service/Action where the Service would
be something like RNet and the  Action something like PIP3A1  (Request
