Configuring Numbering and Versioning Schemes
You can configure the number and versioning scheme used to uniquely identify parts, documents and other objects in the product or library. The numbering and versioning schemes defined at the site and organization level are inherited by products and libraries by default, but each product or library can optionally define its own schemes. Use the Object Initialization Rules Administrator to configure the number and versioning schemes.
In general, when a company is hosting Windchill for its internal use, the numbering and versioning schemes should all be defined in the Site context and should not be overridden by an organization or in a product or library. The Product Design template demonstrates how to set up versioning (and other required functionality) for use in a basic life cycle management environment, where multiple life cycle templates are in use and state-based versioning is set up. If you choose to use this type of environment, consider defining the versioning (and other initialization rules) in the Site context rather than in individual product or library contexts so that all of your products and libraries use the same set of rules.
