The SAP Warehouse Management (WM) module is a solution integrated with SAP ERP, designed to optimize warehouse management processes. By automating and streamlining warehouse operations, this module enables efficient stock management, from planning to execution and tracking of goods movements.
Thanks to its advanced algorithms, the WM module maximizes the use of available storage space. It reduces human error by automating stock management processes, ensuring reliable data and increased accuracy. Automation also speeds up operations, reducing the time required to receive, store, pick and ship goods. In addition, WM provides full traceability of products from receipt to dispatch, improving transparency and control of logistics flows.
Finally, this module integrates seamlessly with other SAP modules, such as Materials Management (MM), Production Management (PP) and Sales and Distribution Management (SD), ensuring smooth and consistent management of the company's operations.

The structure of a warehouse in SAP WM is based on several hierarchical levels, enabling fine, detailed management of storage locations. Here are the main levels :
• Warehouse Number : The main management unit, each warehouse is identified by a unique number.
• Storage sections (Storage Type) : The warehouse is divided into physical or logical areas, such as receiving, picking, bulk storage, etc.
• Storage Bin : Specific locations where goods are stored, each with a unique address in the system.
• Storage unit : Pallets or containers containing goods in storage locations.
• Quants : Smallest identifiable storage unit, corresponding to a batch of goods with the same characteristics (material, expiration date, etc.).
Inventory Management (IM) and Warehouse Management (WM) are two sub-modules of SAP ERP that work together to ensure efficient inventory and warehouse management.
IM manages inventory at the global organizational level. Key features include :
• Stock level management : Monitoring of quantities available in the various storage locations.
• Stock movements : Manage receipts, issues, transfers and stock adjustments.
• Inventory valuation : Calculation of inventory value using different methods (weighted average price, FIFO, LIFO, etc.).
• Stock reporting : Generate reports on stock levels, movements and values.
WM focuses on detailed inventory management at warehouse level. Its main features are :
• Detailed storage location management : Precise definition of zones, locations and sections for optimum space utilization.
• Internal stock movements : Management of stock transfers between different locations within the warehouse.
• Optimization of picking and storage processes : Use of algorithms to improve operational efficiency.
• Handling unit tracking : Pallet and container management for efficient organization.
• Traceability and inventory control : Granular tracking of stock movements for complete traceability.
Integration between IM and WM ensures smooth, consistent inventory management:
• Goods receipts : IM records overall goods receipt, while WM manages detailed putaway.
• Goods issues : IM records the overall issue, and WM handles the specific picking.
• Stock transfers : IM handles transfers between sites, while WM handles transfers within the warehouse.
• Physical inventories : IM manages global inventories, while WM facilitates detailed inventories by location.
