Rollback Method (IMMPxSubtask)

Allows a subtask to recover from failure. If a subtask fails, the Rollback method is called on all subtasks that were previously executed within the task. Rollback is NOT called on the failed subtask. It is the failed subtask's responsibility to recover from its own failure and handle its errors.
