Warehouse Management with Lean WM

Use

When you implement the Warehouse Management System (WMS), you manage goods movements and stock changes in the warehouse at storage bin level. However, if you implement Lean WM, inventory management takes place solely at storage location level. The system does not update the stock data at storage bin level using the quants.
当你实施WMS仓库管理系统时，你的仓库是在仓位级别进行货物移动和库存改变的。然而，如果你实施了Lean WM，库存管理只单独发生在库存地点级别。系统不会在仓位级别上使用份对库存数据进行更新。

You use Lean WM solely for processing goods receipts and goods issues. Using Lean WM, you process the warehouse movements in basically the same way as if using the Warehouse Management System: you work with deliveries, and you create transfer orders for these deliveries. These transfer orders serve as pick lists (see also Using the Transfer Order as a Pick List in Lean WM). We recommend that you implement Lean WM if you wish to pick deliveries in a warehouse that you are not managing using WMS.
你可以使用Lean WM单独地处理发货或及收货。使用Lean WM，你处理货物移动基本上跟WMS一样：处理交货，并对这些交货创建转储订单。这些转储订单可作为拣配清单来使用。如果你希望在仓库中对交货单进行拣配，但又不使用WMS进行管理的话，我们推荐你实施Lean WM。

The use of transfer orders in Lean WM provides the following advantages:

• You can reprint transfer orders at any time.
  在任何时候你都可能打印转储订单。

• You can split transfer orders and thus distribute the workload better among the staff in your warehouse.
  你可以对转储订单进行拆分，从而可以在你的仓管人员之间更好地分配工作量。

• You can pass on the transfer order target data and the names of those who process transfer orders to the HR application component, where this data can be used to calculate incentive wage.

If you do no wish to update stocks in your fixed bin warehouse at storage bin level, Lean WM provides you with the option of using the advantages of warehouse management through transfer orders in the same way as warehouse management using the WMS.

If you are already using the standard WM system, we recommend that you implement Lean WM in a further warehouse where no updating of stocks at storage bin level is necessary. In this way, you ensure that the processes for warehouse management are uniform. in all warehouses.

Since Lean WM does not update stocks at storage bin level, you can display the stock quantities solely in Inventory Management (IM) and not with the stock overview function in WM. Also, you cannot process possible stock differences that occur in the warehouse using Lean WM, only using Inventory Management (MM-IM):

Prerequisites

You can only implement Lean WM in a fixed bin warehouse; random storage is not possible.
你只能在固定仓位的仓库上实施Lean WM，而不能在随意仓储的仓库上进行。

Before you can implement Lean WM, you need to make the following configuration changes in Customizing:

1. Assign a (newly defined) storage location to a warehouse number.
   分配或新定义一个库存地点给一个仓库号

2. Set up at least two storage types:
   建立至少2个存储类型：

• • a picking storage type as the source storage type
    一个拣配存储类型作为源发存储类型（固定仓位005）

  • A shipping area as the destination storage type for deliveries
    一个装运区作为交货的目标存储类型（装运区916）
