Inventory Management is a critical component of Supply Chain Management (SCM) that ensures optimal control over stock levels, improves order fulfillment, and reduces carrying costs. In the context of SAP-SCM, Inventory Management (IM) forms a core functional area that interacts with various other modules such as Materials Management (MM), Production Planning (PP), and Sales and Distribution (SD). Effective inventory management in SAP enables businesses to gain real-time visibility, maintain optimal stock levels, and support smooth logistics and operations.
