You can capture error information for any SIF request invocation that triggers the error mechanism in the Web service—such as syntax errors, run-time errors, and so on.
You can enable auditing for all errors associated with SIF requests.
Auditing errors is a feature that you enable globally. Even when auditing is not currently enabled for a particular SIF request, if an error occurs during that SIF request invocation, then the event is captured in the audit log.
