We are currently implementing Ariba P2P to SAP with Ariba Integration Toolkit on SAP NetWeaver PI.
According to the latest version of the Ariba Integration Toolkit Guide the server and client certificates that the Ariba Integration Toolkit on SAP NetWeaver PI uses to connect to an Ariba solution have been stored in the SAP NetWeaver PI keystore.
However, following testing we had error: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
We then loaded the Base64 encoded certificate in Ariba as well (Integration Manager>Integration Toolkit Security) - unfortunately after testing we had the same error.
If anybody has any experience with configuring Ariba Integration Toolkit on Sap NetWeaver PI and can share any tips and tricks this would be greatly appreciated.
