  * 修复 Bug #503：
  *   【住院发退药】发药明细（OrderDetail）与发药汇总单（OrderMain）数据的触发时机不一致，
  *   可能导致明细已写入而汇总单仍保持旧状态，业务出现脱节。根因是发药业务在同一事务
- *   中先插入明细后异步更新汇总单，异步任务未必及时完成。
+ *   ...
+ *
+ * 修复 Bug #561：
+ *   医嘱录入后，总量单位（totalUnit）显示为 “null”。根因是 OrderDetail 在保存时
+ *   直接使用 CatalogItem#getTotalUnit()，但该字段在诊疗目录配置中可能为空，实际
+ *   应使用诊疗目录的 “总量单位” 配置值（catalog_item.total_unit_config）。
+ *   为避免出现 null，增加容错处理：若 totalUnit 为 null，则回退使用
+ *   totalUnitConfig（或其它业务默认值），确保前端始终能获取到有效的单位。
