I. Understanding Master Data in SAP MM:
A. Definition and Significance of Master Data: Master data in SAP MM refers to the core data elements that are fundamental to procurement and inventory management processes. It includes information about materials, vendors, purchasing processes, and source lists. Master data serves as a foundation for various transactions and activities within the SAP MM module, providing accurate and comprehensive information for effective decision-making. (SAP MM notes)
B. Key Components of Master Data in SAP MM:
- Material Master Data: It contains information about materials, such as their description, classification, dimensions, pricing, and storage details.
- Vendor Master Data: It includes information about vendors/suppliers, such as their contact details, payment terms, delivery terms, and evaluation criteria.
- Purchase Info Records: These records store information about the purchasing conditions and history for specific materials from specific vendors.
- Source Lists: Source lists define the sources or vendors from which materials can be procured and the priority of those sources.
II. Material Master Data:
A. Structure and Organization of Material Master Data: Material master data is structured hierarchically. It is organized into various levels, such as client level, company code level, and plant level, to ensure data consistency and segregation.
B. Key Fields and Attributes of Material Master Records: Material master records contain crucial information about materials, including material type, description, base unit of measure, pricing, valuation data, accounting views, and sales views.
C. Material Types and Their Significance: Material types in SAP MM categorize materials based on their attributes and usage. Each material type is assigned specific attributes and controls the behavior of the material master record in various SAP processes.
D. Views in Material Master Data: Material master data is divided into different views to capture specific information relevant to different functional areas. The key views include:
- Basic Data View: Contains general information about the material, such as description and classification.
- Purchasing View: Includes purchasing-related information, such as purchasing group, lead time, and order unit.
- Inventory Management View: Provides details on storage locations, stock availability, and material valuation.
- Accounting View: Stores accounting-related data, such as valuation class, price control, and cost center assignments.
- Sales View: Contains information related to sales and distribution, such as pricing conditions and sales unit of measure.
III. Vendor Master Data:
A. Importance of Accurate Vendor Master Data: Accurate vendor master data is crucial for efficient procurement processes, as it enables effective communication, contract management, payment processing, and supplier evaluation.
