DRV_VERSION is a derived field displays the version of the build the application is currently running. 

This is derived from the files within the HLAppResources\release\config directory. This version would only be updated during an upgrade of the application.

For example, for professional users, the file __ePersonalityStyle.xml__ contains the following XZML snippet, which indicates the version that will be presented to the professional interface:
{{{
 <versionRules>
    <versionRule application="ProfessionalUI"  productName="ePersonality"   version="4.08.10.07" />      
  </versionRules>
}}}

and the __selfServiceStyle.xml__ files present the version to the Self Service users (in the browser banner)
