How to report on the Session Owner of Messaging Sessions

As a workaround, you can create a custom Formula field on the Messaging Session object to retrieve the Session Owner's name, which can then be used in reports.

STEPS:

1.  On the object Messaging Session, create a new custom field with the data type 'Formula'. 
2.  Use the following formula: (This formula retrieves the first name and last name of the User record associated as the session owner, separated by a space.)

Owner:User.FirstName & ” ” & Owner:User.LastName

       3.  The field should display the name of the Session Owner. 

In your Report, use this field instead of the standard Session Owner field.
