When modeling business processes, modelers tend to describe the best-case scenario - the way the process should proceed. Nevertheless, there may be
- error procedures (compensations) coming from the process itself, or ...
- technical errors during process execution.
On technical errors, the process state machine will change into an Error state. How to handle technical errors within the Error state is described in section Default Error Handling.
How to implement Task Compensations in the process model is described in section Task Compensation.
