## 问题描述
缺料分析如何在完成分析后，附加统计计算相关的采购订单的未入库数量
## 实现方案
本插件的目的主要是基于缺料分析的分析功能完成后，按照缺料分析加载的供应表获取采购订单类型的供应，获取相关联的未审核采购入库单统计数量。原理是：在分析完成后自动调用的保存事件中加入二开插件执行客户化逻辑。注：本方案仅支持补丁号 PT-149006（[8.1.0.20230608] 发布时间:2023/6/8）以后的版本，往前的历史版本获取不到每个子项分配的供应条目。
## 插件样例
扩展缺料分析单，在保存操作上注册新插件，源码参考以下：
其中，detailItems包含的属性可以参考表单【缺料分析子项明细】业务对象，需要加属性可以扩展该表单进行添加
供应表PrepareMtrlCalcBillView.SupplyData可以参考表单【备料运算单据】业务对象的页签分录【供给数据信息】，判定供应是什么类型按照一下属性
RelationFormId//供应单类型
BaseTotalQty;//该供应条目的总供应数量统计
RelationBillNo;//供应的单据编号
RelationInterId;//供应的单据内码
RelationEntryId;//单据分录内码
RelationFormId_Id;//供应单据的FORMID,如即时库存为STK_INVENTORY，采购订单为PUR_PurchaseOrder...
