Idempotent - a repeated call to this method will always return the same
data. The message data is only cleared when a new InvokeService call is
made. References in the RulesMessage table are to the response data
structure used in the InvokeService()} call, which may differ from the
input application data data structure. See the InvokeService
documentation for details.
