What is FI-MM?

FI-MM refers to the integration of SAP's Financial Accounting (FI) and Materials Management (MM) modules. It ensures that financial postings are automatically and accurately created in FI when material movements (goods receipts, goods issues, stock transfers, etc.) occur in MM. This integration is crucial for real-time inventory valuation, cost accounting, and reconciliation between physical stock and financial records, leading to improved accuracy and streamlined business processes.
