组装拆卸单BOM展开，成品表仓库仓位赋值到子件表仓库仓位

【业务背景】组装拆卸单点BOM展开后，表体仓库希望可以获取成品表仓库。目前系统获取的是物料清单上或者是物料上维护的仓库

【问题分析】系统的标准插件逻辑中，BOM展开时，BOM展示时，插件会将子件单据体的数据清空，再根据返回的BOM清单明细，重新创建出子件物料数据。子件表数据设置仓库仓位的处理规则：

1、取组装BOM中子项的仓库设置 

2、子项仓库设置为空，则携带物料的仓库、仓位

根据上述的处理过程，若需要对BOM展开后的数据进行修改，只能通过表单插件，在BOM展开点击，执行完系统的标准逻辑后，二开修改相关数据。

【二开实现】
