Important SAP MM Concepts
Below are some important SAP MM concepts every professional in this field must be aware of.
1. Enterprise Structure in SAP MM
Enterprise structure defines the organizational units in SAP MM. It forms the backbone of the procurement process. The client represents the highest level in SAP. The company code handles financial accounting. The plant manages production and material requirements. The storage location stores physical inventory data. The purchasing organization controls procurement activities. The purchasing group manages buyers and vendor negotiations.
A professional must know how to assign plant to company code. The system links purchasing organization to plant. This assignment enables procurement transactions. Without correct configuration, the system cannot post goods or invoices.
2. Master Data in SAP MM
Master data drives every transaction in SAP MM. It includes material master, vendor master, and purchasing info record. Material master stores all information about a material. It contains views such as basic data, purchasing, accounting, and MRP. Each view serves a specific function. Vendor master stores supplier information. It includes general data, company code data, and purchasing data. The system uses this data during purchase order creation and invoice verification.
Purchasing info record links material and vendor. It stores price and delivery terms. The system fetches this data automatically during procurement. Accurate master data reduces errors and improves automation.
3. Procurement Process in SAP MM
The procurement cycle begins with purchase requisition. A user creates a purchase requisition when there is a material need. The system records quantity and delivery date. The purchasing department converts the requisition into a purchase order. The purchase order acts as a legal document. It contains vendor details, pricing, and delivery terms.
The system posts goods receipt when material arrives. The goods receipt updates stock quantity and accounting entries. SAP creates a material document and accounting document.
Invoice verification completes the cycle. The system matches invoice with purchase order and goods receipt. This process ensures three-way matching. The system blocks invoice if there is price or quantity variance.
4. Inventory Management
Inventory management tracks stock movement in real time. SAP MM uses movement types to control stock posting. Movement type defines transaction behaviour. For example, movement type 101 posts goods receipt for purchase order. Movement type 261 issues material to production.
The system updates stock at plant and storage location level. It also updates stock value in accounting. SAP supports different stock types. These include unrestricted stock, quality inspection stock, and blocked stock. Each stock type controls usability of material.
A professional must understand physical inventory process. The system compares physical count with system stock. It posts differences automatically. This ensures stock accuracy.

5. Valuation and Account Determination
Material valuation determines stock value. SAP MM supports standard price and moving average price. Standard price remains fixed during a period. Moving average price changes after each goods receipt.
Automatic account determination links MM with FI. The system posts accounting entries during goods movement. It uses transaction key and valuation class. OBYC configuration controls this process. Proper setup ensures correct G L posting.
6. Material Requirements Planning Integration
SAP MM integrates with MRP in SAP PP. MRP calculates material shortage. The system generates planned orders or purchase requisitions. It uses data from material master such as MRP type and lot size. The purchasing team converts planned procurement proposals into purchase orders. This integration ensures timely material availability. It reduces production delays.
7. Release Strategy
Release strategy controls approval workflow for purchasing documents. The system uses characteristics such as document type and value. It assigns release codes and release groups.
The purchase order remains blocked until approval. This process ensures internal control and policy compliance. A professional must configure release procedure using classification system.
8. Special Procurement Processes
SAP MM supports subcontracting and consignment. In subcontracting, vendor receives components and returns finished product. The system tracks component consumption. In consignment, vendor stores material at customer site. The customer pays only after usage. SAP tracks liability separately. Stock transfer and third-party procurement also form part of special processes. Each process requires correct configuration and movement types.
9. Reporting and Analytics
SAP MM provides standard reports for stock and purchasing analysis. Professionals use reports like MB52 for stock overview. They use ME2N for purchase order tracking. SAP also integrates with SAP BW and SAP Analytics tools. Real time data helps management take better decisions. Accurate reporting improves supply chain performance.
