Hi Anindya;
Thanks for your question. I reached out to the team working on the Ariba and SAP integration and they provided the following guidance:
Ariba and SAP SNC teams are working together on the Integration scenarios currently. Topics include Supplier On-Boarding, Single Sign-on and Message Integration.
Further details will be provided in Q1, 2014.
If you have additional questions, you may want to contact your Ariba or SAP account rep for further discussions.
Regards,
Debbie Curtis-Magley
