Hi Andreas
This SMSession is a session from the appliction server (I think a Siebel) and your computer to identify the user. Normally it has a connection time so during this time you can access the appliction with the same session ID. The SMSession is created by the server when you access it and depend how was configure the security, this value has different uses.
Please comment/remove it, and check if LoadRunner will use the new one when access the server again.
