SAP WM structure

This blog post contains simple WM organizational chart

The warehouse structure in Warehouse Management is hierarchical and consists of the following elements:

The Warehouse Number
You can define an entire physical warehouse complex in WM using a single warehouse number.
The Storage Type
Each of the warehouse facilities or areas that make up the warehouse complex can be defined as a type of storage area or "storage type" on the basis of its spatial, technical, and organizational characteristics.
Each storage type is divided into storage sections. A storage section generally includes all bins that have certain characteristics in common, such as bins for "fast-moving items" near a goods issue area.
The Storage Bin
Each storage type and storage section consists of a row of storage spaces that are referred to in WMS as storage bins. The coordinates of the bins indicate the exact position in the warehouse where goods can be stored.
The Quant
The quant serves to perform inventory management of a material at the storage bin.
To depict the setup of your physical warehouse in the system, first define the warehouse structures in WMS in the Customizing application. We recommend that you adhere to the following sequence when setting up your warehouse structure in the system.
