 - 采购单和委外单，供应商/物料库、中文 XLS/XLSX 导入。
+- 供应商支持维护公司简称，PDF 下载文件名采用“单据类型_订单号_供应商简称.pdf”；未填写简称时使用供应商全名，已审批文件重新下载也适用。
 - 草稿可暂存，“保存并提交”保证当前修改一起进入审批。
 - 数量、单价四位精度；逐行四舍五入到分再合计，页面、数据库和 PDF 使用同一口径。
 - 制单与审批由不同账号完成，管理员也遵守分工；审批员一次确认即可通过或驳回。

 本包用于在你的 Windows 7 服务电脑上，从 v4 源码生成 EXE。包括 Python 3.8.10 官方完整安装程序、32 位与 64 位离线依赖、构建脚本、环境与业务自检，以及现有 16 页使用升级手册。
 
+2026-09-17 文件名更新：在“供应商管理”的新增或编辑窗口填写“公司简称”，PDF 文件名即为“采购单_订单号_简称.pdf”（委外单使用对应类型名称）；未填写简称时使用供应商全名。已审批订单重新下载也使用新文件名，归档 PDF 内容不变，无需重新审批。Excel 模板新增末列“公司简称”，旧表缺少该列时保留原简称。本次启动会先备份数据库，再升级到数据库结构版本 5，新增简称字段。
+
 2026-09-17 排版更新：采购专用章直径增加 30%，固定在右侧需方签章空位；供方和需方签章区之间留出 20 毫米间隔。采购单与委外订单均已调整，示例见 `samples/`。本次 PDF 模板版本为 `po-v4`。
 
 升级后新审批生成的正式 PDF 使用新排版。已审批归档的 PDF 保留原版；需要采用新版的订单，请通过系统的“变更重审”流程重新审批。使用本包重新解压、安装环境并生成 EXE 后，按下文备份和替换服务程序。
