SAP MM Tutorial for Beginners 2026: Complete Materials Management Guide

I’ve spent 12 years implementing SAP MM at companies like TVS, Ashok Leyland, and Cipla. This tutorial covers what took me years to learn — condensed into a single guide you can finish in a week.

SAP MM (Materials Management) is one of the most stable SAP modules. Every manufacturing company needs it, and certified consultants earn ₹8-25 LPA in India. Let’s get started.

What is SAP MM?

SAP MM handles the procurement and inventory processes for an organization. It covers:

• Purchasing (PR to PO to GR to Invoice)
• Inventory Management (stock movements, physical inventory)
• Material Valuation (costing, price control)
• Invoice Verification (matching, payment blocks)
