Managing Object Initialization Rules
The use of object initialization rules provides a way to specify the following:
Default values for the attributes of a specific object type. The default values are then used when a Windchill solution creates objects of that type and the user interface does not set a value. For example, you can set the default values for numbering and versioning.
Display characteristics that constrain attribute values. If the user interface checks for the constraints, they are then used when the attribute value is displayed in the user interface. For example, the constraints for numbering, and versioning are honored in the user interface.
By default, the object initialization rules established by the site are inherited by each organization context and then inherited by the product or library. However, they can be overridden by an organization or overridden in a product or library. The rules are defined in an XML format and can be viewed and edited by a product or library manager.
