BII Names
Usually, your BII must have the same name as the BID it corresponds to. If your business interface implementation is ‘protected’ or ‘private’ and has another name than the business interface definition, then the business interface implementation name is used as the business object name in LN. In that case your business object will be a protected business object, because it cannot be accessed from the outside through the interface as specified in the BID. For details, refer to section Using Multiple Implementations.
