Spiro T --
In the sample DB, the Project Server administrator created an additional
Version called Target, which probably serves as the original "agreed upon"
version of the project before beginning work. The Published version is
always the current production copy of the project. Your Project Server
administrator could create one or more Versions in your own envrionment,
based on the communication and tracking needs of your organization. If no
custom Versions are created, then the only available project Version will be
the Published version. Hope this helps.
