Can you explain more about EWM’s internal routing features

SAP Extended Warehouse Management (EWM) utilizes internal routing features to optimize material flow within the warehouse. These features include routing guides, which define rules and regulations for shipping goods, and process-oriented storage control (POSC) and layout-oriented storage control (LOSC). Routing guides specify the path or sequence for transporting goods, while PSC focuses on optimizing material flow based on process requirements, such as picking, putaway, and cross-docking, while LOC optimizes material flow based on the physical layout of the warehouse, considering factors like aisle structure and storage zones.
Efficiency of internal routing reduces travel time, minimizes congestion, and ensures optimal resource use. Accuracy ensures goods follow the correct paths, preventing errors and delays. Flexibility allows dynamic adjustments based on changing warehouse conditions. Effective internal routing enhances overall warehouse productivity and contributes to seamless operations.
