Material master

The material master in the SAP system consolidates all important information about a material and stages them centrally for all business processes. It ensures that purchasing, production, warehouse, and sales are working with uniform, consistent data. As such, it forms the foundation for efficient process flows throughout the company.

What is a material master?

The SAP material master is a key data record in the SAP system that contains all significant information about a material. This includes data for procurement, warehousing, production, sales, and assessments, among others. This data is used cross-functionally, ensuring that all enterprise processes – purchasing, production, sales, accounting, and more – run based on uniform, consistent material information.

(Applicable transactions: MM01; MM02; MM03)

How does the material master work?

The material master works like a central data pool, where all the information for a material is saved once and can then be used by all SAP modules. Instead of each department maintaining their own data, the entire system accesses this one, shared record. As a result, no duplicate records or inconsistencies arise.

What are the advantages of the material master?

  • Central, uniform data foundation
  • Support for all business processes
  • Improved data quality and fewer mistakes
  • Transparency throughout the company
  • Support for automation and planning
  • Flexibility thanks to views and organizational levels
  • Foundation for correct bookkeeping and valuation

What are the disadvantages of the material master?

  • High maintenance effort required
  • Complex structure
  • Highly dependent on correct data
  • Potentially redundant or obsolete data
  • (Rigid data models)
  • No automatic quality check
  • Dependency between departments

What are the essentials of the material master?

  • Maintain master data completely and correctly, because it affects many processes.
  • Only create necessary views, to avoid unnecessary complexity.
  • Define clear responsibilities for creation, changes, and release.
  • Use mandatory fields and rules to ensure data quality.
  • Ensure that the material data is maintained regularly and is up to date.
  • Avoid duplicates by searching thoroughly before creating new records.
  • Select the material types correctly, to ensure correct control and valuation.
  • Observe process-dependent fields, for example, for purchasing, production, or warehouse.
  • Lock or cleanse records for old or unused materials.

What is the difference between material master, article master, and product master?

  • Materials are used in the classic SAP ERP and SAP S/4HANA systems. The term describes a physical or virtual object that is managed in a material master. This term is the standard in modules such as MM, SD, and PP.
  • Articles are used in the SAP Retail environment. It represents the retail-specific variant of the material and includes additional functions like variants (such as color/size), assortments, and store processes.
  • Products are used in SAP EWM, SAP CRM, and increasingly in SAP S/4HANA as well. It is a general, cross-system term. A product is managed independently in CRM, while it is derived from a material in EWM.

Is using material masters recommended?

Yes. In fact, using material masters isn’t just recommended; it’s unavoidable, especially at companies that manage many materials or have complex logistics, production, or commercial processes. Using central material masters means all material-related data is only maintained once and then used in all areas – which reduces errors, creates transparency, and makes process flows much more efficient. The material master is essential, particularly at SAP-based companies, because nearly all processes build on it.

What is the right way to use material masters?

To use material masters correctly, maintain all relevant views carefully and completely, to ensure that every department receives reliable, consistent data. It is important to define clear responsibilities for creating, changing, and reviewing the material data. In addition, the data should be updated regularly and adapted to changes in processes. If you do this, material masters will support all logistics and account workflows efficiently and error-free.

How do material masters help in everyday business?

Material masters simplify everyday business, because all departments can access the same reliable material information at all times. In purchasing, for example, it helps to order materials quickly and correctly, without having to search for the relevant data each time. In production, it provides support with the right quantities, MRP parameters, and warehousing data, avoiding delays and poor planning. In the warehouse, it ensures that materials are identified clearly, updated correctly, and found faster. Overall, material masters make workflows more efficient, reduce mistakes, and save employees time and effort day in and day out.
