The strategic placement of received goods, known as putaway, is critical for efficient picking later on. SAP EWM employs sophisticated algorithms for putaway optimization, considering factors such as product characteristics (e.g., size, weight, storage requirements like refrigeration), storage bin availability, and picking frequency. This intelligent slotting ensures that fast-moving items are placed in easily accessible locations, reducing travel time for pickers and improving overall throughput.
Outbound Logistics Excellence
The outbound process, the movement of goods to customers, is where the ultimate value of warehouse operations is realized. SAP EWM provides comprehensive tools to manage picking, packing, and shipping with unparalleled precision.
Picking Strategies
SAP EWM supports a wide array of picking strategies to suit diverse operational needs. These include:
- Single Order Picking: Ideal for high-value or time-sensitive items, where each order is picked individually.
- Batch Picking: Allows a picker to gather items for multiple orders simultaneously, significantly increasing efficiency for high-volume operations.
- Wave Picking: Groups orders into “waves” based on defined criteria (e.g., shipping deadlines, product type, destination). This enables the efficient allocation of resources and optimized picking routes.
- Zone Picking: Divides the warehouse into zones, with pickers responsible for specific areas. Once items are picked within a zone, they are moved to a consolidation point for order finalization.
The system intelligently guides pickers through optimized routes, minimizing travel time and reducing the likelihood of errors.
Packing and Value-Added Services
Once items are picked, EWM facilitates efficient packing processes. This includes the ability to group items into shipping units, select appropriate packaging materials, and perform value-added services (VAS) such as kitting, labeling, or re-packaging. The system can guide packers through the required steps, ensuring consistency and accuracy.
Shipping and Transportation Management Integration
SAP EWM integrates closely with transportation management systems (TMS) to ensure smooth dispatch. This integration allows for the creation of shipping documents, scheduling of carrier pickups, and real-time tracking of shipments.
