Pass User name to external system

Content

Hi All,

 

I have a requirement where i need to pass the name of the person who has created the activity for the technician. I found an OOB field uname which i think is the user name. I am passing this username to the external system in the form of XML But it is giving error of wrong tag name. below is the part of XML :

<activity_id>{aid}</activity_id>

<external_id>{external_id}</external_id>

<username>{uname}</username>

 

Please advice any possible method to pass the value of username to external system
