Well-designed external and Advanced Integration services have modeled faults for business exceptions such as “insufficient funds” and often have unmodeled faults for technical exceptions such as “network failure” issues. When you are invoking services from a process, design your process to deal with both types of faults. Typically, a business exception can be handled in the process flow, such as by returning to a previous step or engaging the user, whereas a system fault might result in retrying the service or engaging a process administrator.
To learn more about how to model fault handling in Business Process Modeling Notation (BPMN), search the IBM® Business Process Manager (BPM) documentation for your release for “Handling errors in services”.

- WebSphere Lombardi exception handling and logging
- “Introduction to enhanced error handling and termination handling” presentation
To learn more about how to model fault handling in Business Process Execution Language (BPEL), search the IBM BPM documentation for your release for “Fault handling in BPEL“.
