All, As part of the discussions around UBL 2.2 a request was received to add a reference to the OrderChange document that was the reason for issuing a OrderResponse(Simple) document. I feel that we have two options for this request: * Add a new specific document reference element to the OrderChangeDocument called "cac:OrderChangeDocumentReference" (which is a DocumentReferenceType) * Provide guidance to use the "cac:OriginatorDocumentReference" element for this specific purpose (linking OrderChange to OrderResponse(Simple) ) Both are valid options so I would like to hear the SC comments on this request before we provide an answer. Can we discuss this on this list (ubl-post-award) until next week Tuesday so we can come up with a recommendation after that. Regards, Kees D. I have cc’d the main UBL list for those people that are not subscribed to the ubl-post-award mailing list. If you would like to comment on this then please subscribe to the ubl-post-award list to keep up to date with what is happing in this subcommittee.
