Publish Course Content SOAP:1,007 SRT: Unsupported xstream found: ("HTTP Code 401 : Unauthorized") '

Hi Experts,

I am facing the issue when i am trying to publish the content and getting the  the message message: 'SOAP:1,007 SRT: Unsupported xstream found: ("HTTP Code 401 : Unauthorized")....

I troubleshoot the problem and found user id provide in the RFC destination was not correct..than i provided my user id and password in the RFC connection. It starts working and able to publish the  content without any issue.

Now i want to replace it with some generic id and As soon as I am providing some generic user id (Even by copying the user with my id "which is working fine with RFC connection") and password to same RFC connection, start getting the same exception.

Please provide your expert view on the same, so that i can resolve this issue.

Thanks..
