docs: // Set an associated billing item to an orphan billing item. Associations allow you to tie an "orphaned" billing item, any non-server billing item that doesn't have a parent item such as secondary IP subnets or StorageLayer accounts, to a server billing item. You may only set an association for an orphan to a server. You cannot associate a server to an orphan if the either the server or orphan billing items have a cancellation date set.
