State-based Revision Sequences by Life Cycle State
The versioning schemes for Windchill PDMLink are identified based on the object type through object initialization rules.
For a specific object type, such as a part or document subtype, each object type can use a specific version scheme referenced by a scheme name.
These version schemes are then identified in an XML file. For example, the out-of-the-box XML file loaded with Windchill PDMLink is:
StateBasedVersioning.xml
This file contains the sequences and seeds (for example, NUMERIC and MILSTD).
* 
To change version schemes, do not manually modify the XML file. Use the steps to load an updated XML file described in Setting Up a File-based or State-based Versioning Scheme.
For information on setting up the state-based versioning scheme that corresponds with the Version Series drop-down list that is available for each state, see Administering the Versioning of Parts, Documents, and CAD Documents.
