Subject: [ubl-psc] Re: Punchout in UBL 2.0
I agree that punchout is not particularly included in the process model document but I think it has had much consideration over the past few cycles of UBL. A punchout-like scenario was one reason to include both BuyerID and SellerID in documents such as Order. The problem, in my view, is that 'punchout' is a loose term. I'd value further use case information on what aspects aren't catered for. Perhaps the use case implied is more one of marketplace than 'punchout' and here we are indeed aware that customisations may be required - for the well considered reason that here there is more impact of the 'blackbox' business system on the document interface. All the best Stephen Green >>> Tim McGrath <tmcgrath@portcomm.com.au> 27/09/05 14:58:49 >>> thanks for the comment, but i am not sure that we are leaving interoperability as "someone else's problem". it is that we see punch out as a tightly coupled activity that is outside UBL's scope as a document exchange standard. we certainly try to address interoperability at the document exchnage level. in case i missed something i will pass this onto our procurement subcommittee who may have more to add.
