Configuration of Material Master in SAP MM

Updated: Sep 28

The Configuration of Material Master in SAP is a pivotal step in fine-tuning an enterprise's ERP system to manage materials effectively. This process involves defining attributes like material types, groups, and classes, as well as specifying crucial data points for accurate categorization and streamlined operations. Proper Material Master configuration establishes a robust foundation for inventory, procurement, and production planning, aligning the ERP system with the organization's unique needs and operational goals.

Path to create the material type

Number Ranges

When we construct a material master record, we identify each material by a unique number known as the material number. There are two methods for assigning a number to a material.


  • External Number Assignment- When constructing a material, you must supply your unique number (including alphabets or digits).

  • Internal Number Assignment- You do not need to specify any numbers when building a material. The system assigns a unique number to the material automatically.


Path to Create Number Range

IMG ⇒ Logistic General ⇒ Material Master ⇒ Basic Settings ⇒ Material Types ⇒ Define Number Range for Each material Type

T.Code: MMNR


STEP 1: On the Display IMG screen, select Define Number Range for Each Material Type, by following the above path.
