二开实现单据录入携带序列号主档备注信息

之前一篇文章说到，将入库单上输入序列号、备注，实现单据保存序列号备注写入序列号主档【二开实现单据保存序列号备注写入序列号主档】

这里继续实现另外一部分需求：在出库单据录入序列号时，自动携带主档备注信息到序列号子单据体备注字段。

【客户需求】非库存更新单据如何增加序列号子单据体 

【实现】

大体思路为：表单插件重写DataChanged事件，监听序列号数量字段FSNQTY, 值变化NewValue > OldValue时表示新添加序列号，根据当前序列号和组织物料数据，读取对应的序列号主档信息回填。

【二开实现序列号单据备注保存写入序列号主档(Python实现)】

1、序列号添加"备注"字段引用属性

2、表单插件逻辑
