Retryability of messages between PolicyCenter and billing system

If there is an integration error, the message error is always retryable. There are no non-retryable errors in the base configuration PolicyCenter/BillingCenter integration messaging.

In some cases, an application creates an activity whenever there is an error, so you do not need to rely on event message administration user interface to see the problem. For example, if a line of business uses renewal offers, suppose the renewal is already non-renewed or otherwise not in a state that supports automatic renewal. If the billing system receives a payment and notifies PolicyCenter, a user must decide what to do. In this case, PolicyCenter creates an activity.
