INS: You will create a new record and there will be no previous existing record

MOD: Existing record wil be come in an editable mode which you can change.

INSS: Inspite of previous existing records of the same type being available in the system, you will still be able to create a new record.

另外，我没去检查是否是增强影响的，或者配置影响的，发现以下问题：

我是批导，输入起止日期和level。

当创建的时候，仅仅是根据起止时间创建了，但是level用的默认值1，而并非Excel上传的level值。

所以当新建的时候，是先创建完成后，再执行一遍修改来修改level的值。

最后PA30去查看的时候就没问题了。

时间有限，仅做记录~
