The release of Windchill ProjectLink  10.0 introduced Enhanced Project Plan (EPP) projects. Projects created in earlier Windchill releases are now referred to as “classic” projects and classic project types are no longer available by default. However, users upgrading to the latest release can continue to run preexisting classic projects, as well as create new projects from imported classic project templates.

If you are running a classic project, you have the option to convert that project to an EPP project. Once converted, you cannot revert back to the classic plan type.

There are 45 such helper classes, listed in the following table.
