All of the subtasks associated with the task are executed in order. If any of the subtasks fail, the Execute method will call IMMPxSubtask.Rollback in the reverse order on all of the subtasks that were executed successfully. Execute will also return false to indicate that the task failed. If all of the subtasks execute successfully and the task has an associated transition, the state of the node for which the task was executed will be changed to the 'To State' of the transition and the Execute method will return true to indicate that the task succeeded.
