It seems that every office manager we spoke to had to have the ability to track which loan officer the applicant was applying under. To facilitate the routing as well as the tracking of applications, we added 2 XML elements to the root <Application> node. These elements do not map to any of the fields on the physical 1003 loan application, they are only there for routing and tracking purposes:
<Application>
...
<Rep_Identifier>
<Source_Identifier>
...
</Application>
Before the final release of the XWeb1003 web service, a new SOAP method will enable client applications to retrieve all applications for a specific <Rep_Identifier>.
