Difference between lots and serial numbers¶
Lots and serial numbers are the two ways to identify and track products in Odoo. While there are similarities between the two traceability methods, there are also notable differences that affect receipts, deliveries, and inventory reports.
A lot usually indicates a specific batch of an item that was received, is currently stored, or was shipped from a warehouse. However, it can also pertain to a batch of products manufactured in-house, as well.
A serial number is a unique identifier assigned incrementally (or sequentially) to an item or product, used to distinguish it from other items or products.

Example
制造商为具有共同属性的产品组分配批号；这可能导致多种产品共享相同的批号。这有助于识别单个组中的多个产品，并允许对这些产品生命周期中的每个步骤进行端到端追溯。
何时使用序列号¶
为单个产品分配序列号的目的是确保每件产品在供应链中的历史都是可识别的。这对于为其销售和交付的产品提供售后服务的制造商尤其有用。
Example
序列号可以包含多种不同类型的字符：数字、字母、印刷符号或三种类型的混合字符。
追溯¶
制造商和公司可以参考可追溯性报告，了解产品的整个生命周期。这些报告包括重要信息，如产品的来源（何时）、存储地点和送货对象。
要查看产品的完整可追溯性，或按批次和/或序列号分组产品，请转至 。这样就会显示 批次/序列号 面板。
在这里，默认情况下会列出已分配批次或序列号的产品。这些产品还可以展开，以显示具体分配给它们的批次或序列号。
要按批次或序列号分组，首先要删除右上角搜索栏中的任何默认筛选器。然后，单击 分组方式，并选择 添加自定义分组，这将显示一个小型下拉菜单。从该迷你下拉菜单中选择 批次/序列号，然后单击 应用。
这样做会显示所有现有的批次和序列号，并且可以展开每个序列号以显示与该分配号码相关的所有产品数量。对于*不*重复使用的唯一序列号，每个序列号应该仅对应一个产品。
小技巧
有关单个批号或序列号的其他信息，请点击批号或序列号的行项目，以显示该特定编号的 批次 或 序列号 表格。在该表单中，点击:guilabel:位置 和 追溯性 智能按钮，查看使用该序列号的所有库存。使用该批次或序列号进行的任何操作也可在此找到。
