我正在设计度假请求。假设用户提交带有休假开始日期和结束日期的休假请求。它属于A组团队。该团队可以安排任务。但如果他们没有安排，请求必须在满足休假结束日期时结束。所以我正在寻找计时器。计时器应从休假开始日期和结束日期开始运行。如果假设A组安排任务，则进入B组.B组只能取消该请求（不需要批准）。如果B组取消请求，则转到groupA工作队列。 A组可以完成任务结束。如果B组没有取消请求，则该请求必须结束。请验证我的工作流程。

答案 0 :(得分：1)
我检查这个模型，它似乎不正确。 我发现了一系列问题：
flow13和flow14应该设置约束，例如：
<conditionExpression xsi:type="tFormalExpression"><![CDATA[${constraint}]]></conditionExpression>您的约束可能包含检查是否已制定计划
你应该在timerstartevent2和timerstartevent3
中设置一些时间限制exclusivegateway2不是必要的
usertask2应该有新的TimerBoundryEvent - 如果他们没有完成任务，这将为groupB中断usertask
我制作了一个应该或多或少的版本;）
