## 字段映射规则

* 任何无法识别的字段名称都需要进行字段映射。
* 一个（1）源字段**不能**映射到多个目标字段
  * *在这个例子中，Issue Date被映射到了Certification Issue Date和Certification Original Issue Date。*
    * **Issue Date** -> Certification Original Issue Date
    * **Issue Date** -> Certification Issue Date
* 多个源字段值**可以**映射到一个（1）目标字段
  * *在这个例子中，Cert Status和Status被映射到了Certification Status。*
    * **Cert Status** -> Certification Status
    * **Status** -> Certification Status
  * 在Excel中，重命名工作表标签名称被视为字段映射问题。
