Hello, basically SAP helps you to separate big messages to specific queues so they are not processed in parallel threads and they dont hung your Java environment.
Based on my experience the certificate connection to Ariba is a very picky moment, it will be necessary if you can add more information to this, like a trace or an error you can find.

Dear Ravikanth
File attachments can be sent to Ariba Network in Base64 format.
You can do the conversion in the message mapping and map the base64 string to the cXML attachment node.
This can help you reducing the load on the PI channel
Thanks and Regards
Sikander
