Process instances that were canceled due to an exception in the service component invocation process can be re-executed not only by the system administrator but also from a service requester.

To re-execute a process instance from a service requester, create a service requester that sends re-execution requests to synchronous (Web Services) standard reception.

If invocation of a service component results in an error and the business process instance ID is returned as error information, re-execute the process by specifying the business process instance ID. The following figure shows re-execution of a request sent from a service requester during SOAP communication.

For details about creating a service requester that requests re-execution of a business process, see 8.2.9 Creating a service requester for requesting the re-execution of business processes (Web Services and SOAP Communication Infrastructure) in the Service Platform Basic Development Guide.
