+
+        关键业务逻辑：operation_id映射
+        =====================================
+        问题背景：
+        1. 原BOM的operation_id指向旧routing_component的自增主键ID
+        2. 复制BOM时，新routing_component会生成新的operation_id（自增主键）
+        3. 需要将旧operation_id映射到新operation_id
+
+        映射逻辑：
+        1. plm_copy_temp_bom.operation_id = 原BOM的旧operation_id
+        2. 通过plm_copy_temp_routing找到旧operation_id对应的operation_no（工序编码，如10、20、30）
+        3. 在新创建的plm_routing_component中，通过operation_no找到新的operation_id
+        4. 将新operation_id赋值给plm_bom_component
+
+        关联条件：
+        - temp_r.tree_id = a.tree_id：确保是同一个物料节点的routing
+        - temp_r.operation_id = a.operation_id：通过旧operation_id关联
+        - temp_r.operation_no = new_rc.operation_no：通过工序编码找到新routing
+        - 其他条件（site、bu_no、part_no等）：精确匹配routing记录
