我需要知道如何在仓库管理系统中实现物品的物理计数功能。

I need to know how to implement the physical count of items functionality in warehouse management systems.

大多数系统有一个文件，使用户能够告诉他们拥有的物品的确切数量（仓库中的物理数量）。它可能被称为"实际库存"，库存开仓，库存调节或其他。然后用户购买和销售商品。 因此增加或减少仓库中的物理数量或物品。如果我想回答"仓库中有多少物品存在"的问题。我会以这种方式计算，（用户创建的最后一个文件中的项目数量（即物理库存））+（购买的数量 - 销售数量）创建文档后。我做对了吗？这是它的实现方式吗？

most systems have a document that enable users to tell the exact quantity of items they have(physical quantity in warehouses). It might be called "physical inventory", stock opening, stock reconciliation or else. Users then purchase and sell goods. Thus increasing or decreasing the physical count or items in the warehouses. If I want to answer the question of "How many of some item is there in the warehouse". Would I calculate it this way, (quantity of the item in the last document(i.e physical inventory) the user created ) + (quantity purchased - quantity sold) after the document is created. Am I getting it right? Is this the way it's implemented?
