单据表单插件用python从临时单据体数据添加到子单据体

业务场景：

    从一个临时单据体“F_cc_Entity”，根据单据体“FEntity”的复选框“F_cc_CheckBox”勾选状态，循环添加到勾选行的子单据体“F_cc_xsm_entry_cf”。

其中有个位置至今还没搞懂为什么：

    在添加对基础资料字段赋值时候，为什么不能用newobject["FBW"]=cfentityRow["FBW2"]，这样会造成保存时候实际上没保存到；不知道是不是因为内存地址都同时指向了临时单据体的DynamicObject原因造成的，但是SetValue又不会？？

代码冗余比较多，听说python写的代码可以短点，如果有大神可以帮忙优化一下的话，请指点下小弟，感激！
