Guidelines for Service Bundles and Simple Service Bundles
The bundling requirements of a service determine whether to define the service as a service bundle or a simple service bundle. When deciding, observe the following guidelines and cautions:
When only one billing product is applicable for a given service, set up the service as a simple service bundle. This restriction applies because a service with a single billing product does not have any associated service-level billing discounts, nor does a need exist to switch from one product variant to another while retaining the same service. Additionally, this product does not need a special rating.
A product that is defined as a simple service bundle cannot be changed to a service bundle. Conversely, a product that is defined as a service bundle cannot be changed to a simple service bundle. Such changes adversely affect the processing of change orders for existing assets. If a change to the product bundling requirements necessitates changing a service bundle to a simple service bundle, or the other way around, then you must define another product in Oracle Communications Billing and Revenue Management, synchronize it with Siebel CRM, and configure it differently.
Because a single asset represents both the service instance and the billing product, you cannot upgrade a customer from a service modelled as a simple service bundle to a service modelled as a service bundle, while retaining the same service instance. You must perform the upgrade through a service cancellation and repurchase.
