# 委外齐套分析下推领料单限制拣货仓库
## 业务场景
委外齐套分析在完成齐套分析后会生成本次领料数，在审核后点击下推委外领料单会根据当前的本次领料数下推委外领料单并进行目标数量的填充。在完成数量填充后，单据转换根据拣货服务，自动按当前的发料组织匹配可用的库存。标准产品在该拣货过程未与委外齐套分析仓库页签勾选的仓库范围联动，导致匹配到不应考虑的仓库库存。
本文提供给一种二开办法来补充实现如何控制拣货服务在限定的仓库范围内匹配库存。
## 实现方案
1.二开委外齐套分析至委外领料单单据转换，传入委外齐套分析仓库页签设置的仓库范围。
2.二开委外领料单拣货服务，加入考虑第1步传入的仓库范围，约束拣货服务获取的库存数据以及先后顺序。
## 详细技术步骤
### 二开委外领料单
加入扩展文本字段，用于下推时填入仓库范围
### 扩展修改单据转换
该插件用于获取源单的仓库范围填充到领料单分录上
