SAP MM Material

In the world of SAP Materials Management (MM), the material master record is the central repository of all information related to the items your organization procures, stocks, and uses in its operations. Understanding material masters is essential for ensuring smooth supply chain processes and accurate data analysis.

What is a Material Master?

A material master is a comprehensive digital record containing every detail about a material including:

• Basic Data: Description, material number, unit of measure, material group/type.
• Procurement Data: Purchasing group, vendors, order quantities, delivery times.
• Inventory Management Data: Storage location, stock levels, reorder points.
• Accounting Data: Valuation class, standard price, moving average price.
• Planning Data: MRP type, lot size, safety stock.
• Additional Views: Data can also include sales-related, forecasting, quality management, engineering, and more.

Types of Materials in SAP MM

SAP MM supports several material types to reflect the diverse items a business might handle:

• Raw Materials: Basic components for manufacturing.
• Semi-Finished Goods: Partially processed, used in further production.
• Finished Goods: Final products ready for sale.
• Trading Goods: Procured for resale without modification.
• Consumables: Items used in operations (e.g., office supplies).
• Services: Non-material items contracted from external providers.

The Importance of Accurate Material Masters

• Streamlined Processes: Correct data ensures smooth purchase orders, accurate goods receipts, and timely inventory updates.
• Reliable Valuation: Precise material data is crucial for inventory valuation and financial reporting.
• Optimized Planning: Material requirements planning (MRP) relies on accurate master data to calculate and procure the needed quantities.
• Data-Driven Decisions: Reliable material information supports better supply chain planning and decision-making.

Creating and Maintaining Material Masters

• Transaction Codes: Use SAP transactions like MM01 (create material) and MM02 (change material)
• Authorization: Access for material master creation and changes is often controlled for data integrity.
• Consistency: Standardized naming conventions, material groupings, and data input rules improve efficiency and reduce errors.

Tips for Effective Material Management

• Regular Data Review: Periodically audit material master data for accuracy and completeness.
• Obsolete Materials: Flag and clean up material masters for items no longer in use.
• Cross-Functional Collaboration: Involve procurement, warehouse, and production teams in defining material requirements and data maintenance processes.
