When working in a project, the system enforces the rule that unclaimed objects cannot be modified. If you select an unclaimed object, the Properties window does not allow you to enter new values for its properties. Similarly, System Editing does not allow property values to flow to unclaimed objects.
If you have a claimed object that is connected to some unclaimed objects, and if you change a property on the claimed object, propagation will not change the property value on the unclaimed objects. The items in the propagation scope are initially collected using the standard propagation rules. However, all unclaimed items are removed from the propagation scope before any property values are changed.
Items that are claimed for relationship are treated as unclaimed for the purpose of propagation.
