Material Master Overview

Material Master is a central repository in SAP that contains all materials that a company procures, produces, or sells. It includes various views maintained by different departments with specific data relevant to their functions.

Configuration Settings

Material Type Configuration

Material type controls the behavior of materials including:

  • Number Range Assignment: Controls which numbers can be assigned
  • Available Views: Determines which screens/views are available
  • Field Control: Makes fields mandatory, optional, or display-only
  • Procurement Types: Determines if material can be procured externally, internally, or both
  • Default Values: Sets initial values for fields like price control

Path: SPRO > Logistics General > Material Master > Basic Settings > Material Types

Field Control Configuration

Field control determines whether fields are:

  • Required: Must be filled (mandatory)
  • Optional: Can be filled or left blank
  • Display: View-only, cannot be changed
  • Hide: Not visible on screen

Field control is defined through field reference keys assigned to material types.

Path: SPRO > Logistics General > Material Master > Basic Settings > Field Selection

Purchase Value Key

Purchase Value Key controls:

  • Underdelivery Tolerance: How much less than ordered can be accepted (e.g. 50%)
  • Overdelivery Tolerance: How much more than ordered can be accepted (e.g. 100%)
  • Deadline Monitoring: When to send reminders to vendors
    • First Reminder: Days before delivery (e.g. -5)
    • Second Reminder: Days after delivery (e.g. +2)
    • Third Reminder: Days after delivery (e.g. +7)

Path: SPRO > Materials Management > Purchasing > Purchase Value Key

Material Ledger Activation

Material Ledger is mandatory in S/4HANA and must be activated for all materials that have quantity or value updates. Key points:

  • Material without Material Ledger activation cannot post any transactions
  • Material Ledger allows multiple currency and valuation views
  • Activation is controlled at plant level and material type level

Configuration path: SPRO > Logistics General > Material Master > Basic Settings > Valuation > Activate Material Ledger

Key Concepts

Different departments are responsible for maintaining specific views in Material Master:

  • Basic Data: R&D Team Provides material specifications, descriptions, weights, etc.
  • Purchasing: Procurement Maintains procurement-related data
  • Sales: Sales Team Maintains sales-related information
  • MRP: Planning Team Controls material planning strategies
  • Storage: Warehouse Team Manages storage conditions and inventory
  • Accounting: Finance Team Maintains valuation and costing

While MM Consultants may technically create the material in SAP, the data should come from the appropriate departments.

Materials can be extended to:

  • New Plants: When a material needs to be used in a different manufacturing facility
  • New Storage Locations: To enable inventory in additional warehouses
  • New Views: When adding functionality (e.g., adding sales views to a previously purchase-only material)

Transaction Codes for Extensions:

  • MM01: Used for extending to new plants or views
  • MMSC: Used specifically for extending to storage locations

Note: MM02 is used for changing existing data, while MM01 is used for adding new views or organizational levels.

Number range concept for materials:

  • Each material type can be assigned to a number range group
  • Number range groups contain one or more number ranges (intervals)
  • Number ranges can be internal (system-assigned) or external (user-assigned)

Configuration path: SPRO > Logistics General > Material Master > Basic Settings > Material Types > Define Number Ranges for Material Types

Typically, companies use structured numbering schemes that encode information about the material, such as:

  • First digits: Material category
  • Middle digits: Sub-category
  • Last digits: Sequential number

Example: 1001-RM-001 (where 1001=Plant, RM=Raw Material, 001=Sequential)
