How to define sub task or child task

Hello,

Could you please some one can guide me, is there any way to define sub task or child task in BPMN flow. I have scenario like the task should have 3 sub task and the parent task should be able to complete once all the 3 subtask are completed.

Is there any way?. thanks in advance.

No, BPMN has no concept of a subtask. The Flowable TaskService api can add subtasks, but this can’t be modeled.
