Subject: Re: PIP IDs
Arvola, 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.

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 action. 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 other words one execution of a PIP is a conversation. I believe that some of the PIPs include multiple business transactions.
