Material master data in sap mm

Master dataMaster 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.

Material Master Data

Different types of master data in sap mm:Material masterVendor masterPurchase info recordSource listQuota arrangementBatch masterService masterCondition master

Transaction data:Data relating to the day-to-day transactions

e.g. Creating PO , PR , MIRO Etc

MaterialGoods 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

Material MasterThis 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.

Material TypesMaterials 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 TypesTCode: OMS2

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 

Material GroupsMaterial 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 GroupsTCode: OMSF

Material group : 9 character alphanumericDescription : 20 character alphanumeric

Number RangeWhen 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)

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 TypeTCode: MMNR

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.

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 MaterialTCode: MM01

Note: For any create transaction we use 01, for edit 02, for display 03 as suffix.

Material master comprises: ConfigurationField selectionBasic settingsToolsEnhancements

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.
