In the System file properties, the display-only properties under Version Information are basically the same as those for the Project. They provide an audit trail of the conversions performed on the System file. For more information, see Version Information Project Properties.

However, if the Project is created from a Windchill product, a fifth display-only property, Windchill PDMLink/MPMLink Settings, is shown. This property indicates the Windchill part selected for the top-level item. Additionally, it shows the saved expansion criteria that was selected for importing its BOM (bill of materials) into the System file. For more information, see Creating a Project or Additional System File from a Windchill Product.
