We are integrating SAP with ARIBA system. We use Service Consumers to get Supplier Profile information from ARIBA to SAP. The Service Consumer has From date, RealmName and To Date field as input. Can anyone let me know what is RealmName and should it be configured in SAP? We use a specific realm "urn:ARIBA:Sourcing:vrealm_****" for RealmName but get any error MISSING_NAMESPACE urn:Ariba:Sourcing:vrealm_**** (The method is trying to access to the wrong realm). Can anyone pls let me know what could be the issue.
