+# 物料供应商、制造商与重复检查实施计划
+
+> **执行说明：** 按任务逐项实施；本次在当前会话中直接执行。
+
+**目标：** 为物料新增/编辑及 Excel 导入增加可选供应商和制造商，并检查物料名称、规格、单位、供应商、制造商五项完全相同的记录。
+
+**实现方式：** 复用 `materials.supplier_id` 和 `materials.manufacturer_id` 关联当前公司的伙伴记录。扩展物料请求、读取和保存流程，并在服务端校验伙伴所属公司和角色。单条新增发现重复时由界面提示确认；批量导入发现数据库或同一文件中的重复行时，按现有整批校验规则返回行号并取消整批写入。
+
+**技术栈：** Go、MySQL、Vue 3、Element Plus、Excelize。
+
+**需求依据：** 2026-10-13 会话中用户确认的规则和字段范围。
+
+## 全局约束
+
+- 供应商和制造商均为选填。
+- 仅当名称、规格、单位、供应商、制造商全部相同时，判定为重复。
+- 伙伴必须属于当前公司，并具有对应的供应商或制造商身份。
+- 保留工作区中已有的未提交修改，不覆盖无关内容。
+- 按本会话要求，不新增或运行测试。

+
+- [ ] 在物料实体和新增/更新请求中加入两个可选 ID。
+- [ ] 在新增、查询、列表、更新 SQL 中读写数据库已有的两个字段。

+- 与已有物料或本文件较早行完全重复时，返回对应行号；任一行出错则整批不写入。
+
+- [ ] 更新模板表头、填写说明、示例行、解析器和错误数据。
+- [ ] 将伙伴名称或编码解析为当前公司的伙伴 ID，并报告无效或身份不符的输入。
+- [ ] 批量读取已有物料判重，并检查本文件内前序行。

+企业资料继续共用 `business_partners`，供应商、制造商、客户身份保存在 `organization_partners`。新增 `is_manufacturer BOOLEAN NOT NULL DEFAULT FALSE`，三个身份可同时存在；旧数据不会自动变成制造商。
+
+`materials.supplier_id` 表示默认供应商，`materials.manufacturer_id` 表示制造商，两个字段都是可空 BIGINT，引用 `organization_partners.id`，不是 `business_partners.id`。`manufacturer_model` 表示厂家型号，即制造商为其产品指定的型号或订货识别型号；它是物料上的文本信息，不是制造商关联 ID。它与 `spec`（物料规格）含义不同，例如规格可填写“M8×30”，厂家型号可填写制造商提供的产品型号或编码。
+
+组织关联表增加唯一键 `(organization_id,id)`；物料通过 `(organization_id,supplier_id)` 和 `(organization_id,manufacturer_id)` 复合外键保证引用属于同一组织，删除或修改被引用的关联键会被拒绝。角色匹配需要由业务接口校验，外键本身不验证 `is_supplier` / `is_manufacturer`。
+
+现有 `material_suppliers` 继续保存多个供应商的价格与供货条件；物料的 `supplier_id` 只表示默认选择。已有库使用 `scripts/upgrades/2026-10-12-material-partner-roles.sql` 升级，空库使用 `scripts/init.sql`。
