• The transaction data message from ERP is not sent to Procure to Pay (P2P) or Sourcing non-US data center realms.

• How can I post documents to my non-US Data Center realm via Managed Gateway for Spend&Network?

Starting from Managed Gateway for Spend&Network 2006 release, adding non-US Data Center realm to trading partner properties is automated. When you enable Managed Gateway for Spend&Network from AN, P2P or Sourcing realm, an entry will be added to the trading partner properties automatically. It is no longer necessary to raise a Case.

Disabling and enabling Managed Gateway for Spend&Network again will trigger the automatic process even for releases newer than Managed Gateway for Spend&Network 2006. Please see FAQ How to enable Managed Gateway for Spend&Network in Ariba? to enable Managed Gateway for Spend&Network again from your realm and update the trading partner properties for non-US Data Center realms.
