SAC Ariba Connection - OData Details

Hello SAP Experts,

I want to connect Ariba to SAC via OData. I read in this forum that it is possible, but I don’t know how to establish the connection.

I have a user for the Ariba developer portal and created an application. All I need is a guide or information on which authentication type and which parameters are necessary to connect Ariba and SAC. Can someone help?

Thanks,

Thorsten.
