here some updates from the supplier side:
Order change problem resolved (missing version)
When the buyer uses the Ariba PO/PI adapter (CI-9 SP2) and the supplier the business suite add-on, it was not possible to process order changes sent by the buyer. The Inbound cXML for Update Purchase Order is not processed on the supplier system. This was due to a missing version attribute in the cXML created by the buyers PI adapter.
Fortunately, SAP provided a solution to this issue with note 2737856 – Duplicate incoming order XX_XXXXX already created with SO number XXXXX
End of maintenance date change for business suite add-on!
SAP changed the end-of-maintenance date from 12/31/2019 to 12/31/2020! See note 2705047
