The WS-BPEL 2.0 specification defines a standard set of faults. Each of those faults is defined to represent an erroneous behavior that could occur during a business process execution. Examples of such standard faults include the following:
correlationViolation

or in an assignment, encounters an errorThese faults are generated by BPEL at runtime.
