Master data in SAP provides essential reference information for transactions and includes different types like material, customer, and vendor master data. The document focuses on material master data in SAP MM, which defines key attributes of materials like the material number, type, and purchasing information. It describes how material master records are configured and organized into views for basic data, purchasing, sales, and MRP information to support procurement, production, and inventory management processes in SAP.

1. Master data
Master data in SAP is used as a base for any
transaction. If you are producing, transferring stock,
selling, purchasing, doing physical inventory, whatever
your activity may be , it requires certain master data to
be maintained. We have material master data,
customer master data, vendor master data,
pricing/conditions master data, warehouse
management master data (storage bin master data)
etc.
The ones we will focus in MM module are material
master and purchase info record.

Data

6. Different types of master data in sap mm:
 Material master
 Vendor master
 Purchase info record
 Source list
 Quota arrangement
 Batch master
 Service master
 Condition master

7. Transaction data:
Data relating to the day-to-day transactions e.g.
Creating PO , PR , MIRO Etc

8. Material
Goods or objects that are used, consumed or created
during the manufacturing may be called the materials
Material can be traded , used in manufacture,
consumed and produced
A Service may also be treated as material

9. Material Master
 This is the enterprise main source of material specific data.
This data will include information on the materials that a
company can procure, or produce, or store or sell.
 Since there are different departments in an enterprise and
each department works on some specific material. So they
will enter different information regarding their material.
So each user department has its own view of material
master record. So, the data screens that are used to create
material master can be divided into two categories:
Main Data: This will include basic data (base unit of
measure, weight), purchasing data (over tolerance and
under tolerance), accounting data (standard price, moving
price).
Additional Data: This will include additional information
like short description about material, currency etc.

10. Material Types
 Materials with some common attributes are grouped
together and they are assigned to a material type. This will
differentiate materials and allow organization to manage
different materials in systematic manner in accordance to
company’s requirement. For example: Raw Material,
Finished Products are some of the material types. Material
type can be created by following the below steps.
 Path to create material type:
IMG >= Logistics General >= Material Master >= Basic
Settings >= Material Types >= Define Attributes of
Material Types
TCode: OMS2

11. Standard SAP Material Types include:
 ABF - Waste
 ERSA - Spare Parts
 FERT - Finished Product
 HALB - Semifinished Product
 HAWA - Trading Goods
 LEIH - Returnable packaging
 NLAG - Non-stock materials
 PIPE - Pipeline materials
 PLAN - Trading goods (planned)
 ROH - Raw materials
 UNBW - Nonvaluated materials

14. Material Groups
Material group is a wider range of material type.
Materials with some common attributes are taken
together and they are assigned to material group
Path to Create Material Group:
IMG => Logistic General => Material Master =>
Settings for Key Fields => Define Material Groups
TCode: OMSF
Material group : 9 character alphanumeric
Description : 20 character alphanumeric

16. Number Range
When we create material master record every material is
recognized by a number, that number will be unique
and known as material number. We can assign number
to material through :
i. Internal (System assigned internal by unit number)
ii. External (With alphanumeric combination with in
defined interval)
iii. External (Alphanumeric number assignment with out
check)

17. Define Number Range:
Internal number range can be defined by following the
below step:
Path to Create Number Range:
IMG => Logistic General => Material Master => Basic
Settings => Material Types => Define Number Range
for Each material Type
TCode: MMNR

19. Material Master Views:
In this section, we will cover all the MM views with the implication
on vital processes in standard SAP system. You will see how each
of the views is created, its obligatory data, optional fields, and
how its creation reflects the system.

21. Material Master Creation
Material master contains all materials that a company
procures produces or sells. Material Master is a central
data that is available at all the levels. Material can be
created by following the below steps:
 Path to create Material Master:
Logistics => Materials Management => Material
Master => Material => Create Material
TCode: MM01
Note: For any create transaction we use 01, for edit 02,
for display 03 as suffix.

23. Material master comprises:
 Configuration
 Field selection
 Basic settings
 Tools
 Enhancements

24. Industry sector :
Branch of industry.
 The industry sector groups together companies according to their activities (for example,
plant engineering and construction, mechanical engineering, the chemical industry, and
the pharmaceutical industry).
 Table-driven program support is provided according to industry sector; for example, for
the selection of data fields on-screen, for the sequence of the screens, and for the
allocation of a material to a material type.
Industry Sector :
 Key that specifies the branch of industry to which the material is assigned.
Use
 When you create a material master record, the industry sector you specify determines
 which screens appear and in what order
 which industry-specific fields appear on the individual screens.

26. Basic Settings:
Define output format Material Number:
Path: SPRO -> Logistic - General -> Material Master ->
Basic Settings -> Define Output Format of Material
Number
TCODE: (OMSL)
i. Lexico graphical
ii. Leading zero’s

28. Maintain company code for materials
management:
Path: SPRO -> Logistic - General -> Material Master -> Basic
Settings -> Maintain company codes for materials
management
TCODE: (OMSY)

i. Setting up company code for material
management
ii. Changing ABP (or) DBP
