The rethrow activity rethrows faults originally captured by the immediately enclosing fault handler. Only use the rethrow activity within a fault handler (for example, within catch and catchAll activities). The rethrow activity is used in fault handlers to rethrow the captured fault (that is, the fault name and the fault data (if present) of the original fault). The rethrow activity must ignore modifications to fault data. For example:

• If the fault handler modifies fault data and then calls a rethrow activity, the original fault data is rethrown, and not the modified fault data.

• If a fault is captured using the functionality that enables message type faults with one part defined using an element to be caught by fault handlers looking for the same element type, then the rethrow activity rethrows the original message type data.
