Efficient warehouse management is crucial to the success of a company. Without reliable inventory management and well-functioning internal warehouse processes, satisfactory customer deliveries cannot be made. In today's world, fast and error-free delivery has become enormously important as the competition is just a mouse click away. Choosing the right warehouse management system is therefore essential for companies that want to remain future-proof and competitive in the market. Warehouse Management, Extended Warehouse Management or Stock Room Management - these are today's SAP warehouse management systems. Each has different features and functions that need to be examined more closely and analyzed with regard to the processes in one's own warehouse. Only in this way can efficient warehouse management succeed without unnecessary additional costs.
