IWDClientUser user = WDClientUser.getLoggedInClientUser();

IUser iuser = user.getSAPUser();

String userid = iuser.getDisplayName();

wdContext.currentZemp_Dob_Alerts_InputElement().setUname(userid);

IWDMessageManager manager = wdComponentAPI.getMessageManager();

manager.reportSuccess(iuser.toString());
