In SAP R/3 a warehouse is structured as follows: 
 
The Warehouse Number
 
A single warehouse number is sufficient to manage entire physical warehouse complex in SAP R/3. 
 
IMG -> Enterprise Structure -> Definition -> Logistic Execution -> Define, copy, delete, check warehouse number -> Copy/delete/check warehouse number 
 
Transaction code: EC09 
 
The Storage Location
 
In order to manage General goods movement process in the warehouse management, we need to create and assign a storage location to warehouse.
 
IMG -> Enterprise Structure -> Definition -> Material Management -> Maintain Storage Location 
 
Transaction code: EC09 
 
The Storage Type
 
A warehouse number is subdivided into a variety of storage types. A storage type is defined by its physical or organizational features (for example, high rack storage area, bulk storage, and goods receipt areas). It can be defined on the basis of its organization characteristics. 
 
IMG -> Logistic Execution -> Shipping -> Picking -> Lean WM -> Define Storage type 
 
The Storage Bin
 
The storage bins indicate the exact position in the warehouse where goods can be stored. Each storage type and storage section consists of a row of storage spaces that are referred to in WMS as storage bins. 
 
IMG -> Logistic Execution -> Shipping -> Picking -> Lean WM -> Define Storage Bin 
 
The Quant
 
The quant serves to perform inventory management of a material at the storage bin. 
 
IMG -> Logistic Execution -> Shipping -> Picking -> Lean WM -> Define Quant 
 
Assigning Warehouse No. to Plant-Storage Locations
 
By doing so, system can recognize which storage locations in Materials Management are controlled by the Warehouse Management system; you must assign the plants and the storage location to the warehouse number. 
 
IMG -> Enterprise Structure -> Assignment -> Logistic Execution -> Assign warehouse No. To plant/storage Location
