需求场景

计划员释放订单时,如果下层组件在不合格库存中有库存时,应先确认不合格库存地库存是否可用,已避免重复生产和库存积压.
因此,提出此需求:
在生产订单下达(释放)时,要提示下层组件在不合格库存地的库存数量.

---

一、实现的效果

先上图,如下图所示,点击释放按钮后,会弹出窗口,显示组件在不合格库存地点中的库存.

二、实现步骤

1.创建自建表

因特定库存地通常不只一个,而且会经常变动,所以做个自建表,存储需要检查的库存地点.
自建表ZTPPDS_026结构如下:

2.增强代码

增强点:WORKORDER_UPDATE(事务代码:SE18),在AT_RELEASE方法中进行增强.

代码如下（示例）：
