Certificate Sharing

Hi All Experts,

I am working on a scenario where my SAP-PI 7.3 dual stack make a connection with external landscape SAP-PI 7.1. I have certain doubts ringing

on my mind

1.I decided to use SOAP receiver adapter, transport protocol as HTTP and message protocol as SOAP 1.1. Is this fine??

2.Since we are communicating with an external landscape SAP-PI using certificate handshaking ,

can any one describe what are the steps involved in it to share each other certificate?

Regards

Alice
