Numbering schemes control how numbers are generated for parts, documents, CAD documents, managed baselines, and change objects. Each object class has its own numbering scheme.

For all Windchill solutions, a rules load file sets the initial numbering rules for documents, CAD documents, parts, and change objects. These rules affect the following:

The loaded numbering schemes for parts, documents, CAD documents, managed baselines, and change objects are simple Oracle sequences that have been loaded into the Windchill database. Each starts at 1 and increments by 1. This means that the numbers for all parts, documents, CAD documents, managed baselines, and change objects are autogenerated according to the numbering scheme that is in place.

To change an out-of-the-box numbering scheme, you can change to a scheme that is defined for you or you can define your own scheme. You can view the rules that are being used for numbering from the Object Initialization Rules table using the Object Initialization Rules Administration utility.

Object initialization rules can be set in context templates or by using the Object Initialization Rules Administration utility from within a specific context.
