Managing Organization-level Object Initialization Rules
You can configure how attributes (such as number) are displayed and generated using the Object Initialization Rules Administration utility. This utility defines how the initial attribute values for the object are established, how the attributes are displayed, and can determine basic relationships, such as life cycle association, when an object is created.
The Object Initialization Rules Administration utility is available from the Site 
or Organizations 
Utilities page. The rules established by the parent site are inherited by each organization context by default, but they can be overridden at the organization level. The rules are defined in XML format; you can view and update them.
