需求:
ECN执行能像时间表任务一样前驱后续并发执行
前提：
首选项：CM_validate_changeNotice_dependency=true
首选项说明：Value of true, activates Change Notice Revision dependency assertion when adding a release status to the Change Notice Revision.
The addition of the release status will not be allowed if the Predecessor Change Notice revisions are not already released or in the target list of the current workflow adding the release status and if the Concurrent Change Notice Revisions are not also in the target list for the current workflow adding the status.
Furthermore, if this site utilizes the release status progression path xml to define release status relative maturities then the release status being added must be the same or lesser maturity than that of the predecessor Change Notice Revisions release status.
The default value is false (not activated).
操作：
- 设置前去后续并发ECN
- 检查效果：触发一个后续相依性的ECN，点执行关闭该ECN
- 上图报错，提示前驱ECN未完成—效果达成
