Possible Scenarios Based on Storage Locations 
The following scenarios based on storage location assignment are provided as examples for implementation in your warehousing complex.
Scenario 1:
One Storage Location per Plant in One Warehouse Number
For this scenario, other than the assignment of the plant/storage location to a warehouse number, there are no additional customizing settings necessary. Within the transactions of WM nothing must be entered into the field Storage Location since the storage location is unique and can always be taken from the values assigned to the warehouse number and the plant.
Scenario 2:
Several Storage Locations per Plant in One Warehouse Number
The storage location displays the actual owner of the stock. Stock movements between the storage locations are always initiated via postings in the Inventory Management component. For this scenario, you need to assign the corresponding plant/storage location combinations to the warehouse number. Additional customizing activities are not necessary.
In this scenario, the system can no longer determine the storage location from the contents of the fields Plant and Warehouse number automatically. When the system creates transfer orders for deliveries or transfer requirements, it copies the storage location from the reference document. When you create transfer orders without a reference document manually, you must enter the storage location in addition to the plant. For inventory taking, this is also necessary for stock that is found in a storage bin that is not in the system.
Scenario 3:
Several Storage Locations per Plant in One Warehouse Number (where the stock is managed differently in interim storage types than in the warehouse itself)

For this scenario, there are two examples:
Example: Stock Movement from GR Area Example: Material Staging for Production
