Symptoms
Get Originator's Manager Full Name in K2 for Sharepoint
Diagnoses
Once the logged in user is obtained. They wanted to also grad the Manager Name (DomainUsername) and convert that information to a displayname.
Resolution
The best way to grab the full name/email of the manger is to pass the "Name" property back though the same smartobject you used to grab the users information. For example, you get the users information from either UMuser or SharePoint 2013 Management > User. Once you have the property for the Manger, you'll then pass that manager information through the same SmartObject UMuser/SP 2013 > User, to get their detailed information.
