SAP Warehouse Management system (WMS) 

With the SAP Warehouse Management system (WMS), you can benefit from automated and flexible assistance for managing stock and processing goods movements within your warehouse complex. The system offers efficient scheduling and processing of all logistics processes in your warehouse, allowing you to optimize your operations. 

The WMS is seamlessly integrated into the SAP environment, which means that when you initiate business processes in other application components, they will trigger physical goods movements in your warehouse. With the WMS, you can easily organize, control, and monitor these goods movements, providing you with greater visibility and control over your warehouse operations. 

Main Features of WMS include:

Storage Bin Management

Storage Bin Management

By mapping out your entire storage facilities in the Warehouse Management system, you can create different types of storage facilities, such as automatic warehouses, high rack storage areas, bulk storage, or fixed storage bins, tailored to your specific requirements. This enables you to effectively manage your inventory and optimize your storage capacity. 

With the Warehouse Management system, you have the ability to manage your material stocks at the storage bin level and customize your storage bin configurations to meet your specific needs. By mapping every storage bin in your warehouse in the system, you gain comprehensive visibility of all stock movements, allowing you to easily locate any product within your warehouse. 

The Inventory Management and Warehouse Management systems are fully integrated, ensuring that the inventory balance in Inventory Management always matches the warehouse stock in the WMS. This is achieved through the WMS's physical inventory procedure and recording of any stock differences, thereby maintaining accurate and up-to-date inventory records. 

Goods Movements

Goods Movements

The Warehouse Management system facilitates all goods movements related to your warehouse operations, such as goods receipts, goods issues, stock transfers, material staging for production, automatic replenishment, management of hazardous materials, and processing of stock differences. 

Using putaway and stock removal strategies tailored to your specific needs, or alternatively using storage units, the Warehouse Management system effectively optimizes warehouse capacities and material flows. 

Physical Inventory

Physical Inventory

Regular physical inventory is conducted in your warehouse to verify the actual physical stock against the data recorded in the WMS. Any discrepancies are then identified and recorded through the entry of physical inventory differences, which helps to ensure accurate accounting of stock in accordance with the results of the physical stock take. 

Planning and Monitoring

Planning and Monitoring

With the WMS, you have access to a comprehensive overview of all goods issues and warehouse stocks, allowing you to effectively plan, monitor, and optimize your work processes. The system provides valuable insights such as workload projections for upcoming days and alerts for critical warehouse processes, enabling you to take corrective actions in a timely manner of warehouse movements. Additionally, the RF monitor provides you with real-time updates on all warehouse activities, enabling you to exercise control over actual work in the warehouse. 

Radio Frequency Connection

Radio Frequency Connection

To ensure efficient and cost-effective work processes in the warehouse, you can easily and clearly manage the work steps of warehouse workers through mobile radio-frequency terminals. 

By establishing a radio frequency (RF) connection, mobile data entry ensures fast and accurate data transfer. The RF devices receive data directly from the SAP system and transmit data back to the system. Barcodes are used to capture and verify information, allowing you to maintain a high level of accuracy and quality in your warehouse operations. 

Warehouse Control

Warehouse Control

The WMS is equipped with an interface to external systems, such as warehouse control units, enabling you to seamlessly integrate automatic putaway, stock removal, or forklift control systems into the warehouse management system for all warehouse movements. This is made possible using the ALE (Application Link Enabling) interface.
