Hello Allen,

I really appreciate the feedback.  Everything you said makes sense to me except for why the user_name field is working, along with email_address, and name fields, but yet the employee_number field does not.  I guess I was hoping for a setting in the system that currently contains user_name, email_address, name, then I could just add employee_number.  We were hoping we didn't have to query the users table first.  By the way, the display field on the sys_user table is name.


Example of the email address working:
{
"assignment_group": "Presidents",
"assigned_to": "abraham.lincoln@example.com"
}

Returns this:

{
  "result": {
    "assigned_to": {
      "display_value": "Abraham Lincoln",
      "link": "https://xxxxxx.service-now.com/api/now/table/sys_user/a8f98bb0eb32010045e1a5115206fe3a"
    }
  }
}
