Exception Handling

SOAP Web Services allow for a notify/response transaction model.

For PRs, POs and Invoices – immediate feedback is provided to the initiating system (though the Maximo/PeopleSoft user interface is not currently automatically updated based on the reply)

Errors are routed - through e-mail messages - back to the business experts that will know best how to resolve the issue.
