Introduction to SAP MM SAP MM is known as SAP Material

Management system. SAP MM role in business process is as follows:

A business process in SAP is termed as “Module”.

SAP Materials Management (MM) is a part of Logistics area and helps to manage the procurement activity of an organization from procurement.

It supports all aspects of material management (planning, control etc).

It is the backbone of the Logistics area which incorporates modules like Sales and Distribution, Production Planning, Plant Maintenance, Project Systems, Warehouse Management which are extremely obsessed on Materials Management module.

Features of SAP MM SAP MM is one of the modules of SAP

that deals with material management and inventory management.

Material Management process ensures that there is never a shortage of materials or any gaps in the supply chain process of the organization.

It deals with managing the materials (products and or services) resources of an organization with the aim of accelerating productivity, reducing costs and increase improvement and at a similar time be versatile to accommodate changes in day to day life.

It deals with the Procurement Process, Master Data (Material & Vendor Master), Account Determination & Valuation of Material, Inventory Management, Invoice Verification, Material Requirement Planning etc.

Introduction To Master Data

What is 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.

Types Of Master DataSAP Master Data is of following two

types: Material Master Data Vendor Master Data

Material Master Data The key points about material master are as

follows: 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. 

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.

Vendor Master Data The key points about vendor master

are as follows: This is the enterprise main source of

vendor specific data. This data will include information on vendors from which a company can procure or it can sell.

Vendor Master Record will contain information like vendor's name, address.

Data in vendor master record is divided into three categories:General Data: General data is maintained at client level and it is valid for all organizational levels.Accounting Data: Accounting data is maintained at company level and it is valid for all plants belonging to that company.Purchasing Data: Purchasing data is maintained at purchasing organization level.

How to Create Material Master Data

When we want to use a new material in SAP, we have to define it's characteristics, in order to control it's behaviour in all of the transactions. Every material is created in the either of these two ways:

By calling transaction MM01 (mostly used in a productive environment)

Mass creation (mainly used only once on transition of materials from the previous system into SAP ERP)

We will focus now on transaction MM01, and leave the mass creation for later since it is an advanced tool. We will discuss it after you have enough knowledge about material master views and organizational levels.

Step 1) Transaction that is used for the creation of material master record, as stated above is MM01. The execution of the transaction brings us to the initial screen, which consists of few fields that contain the basic information on our material.

Enter Industry sector (mostly used: M-Mechanical engineering)

Enter Material type, (it can be FERT, ROH, HALB, HAWA - the appropriate material type for current material)

Step 2) We can choose which master data to create.

We can click on Select View(s) to choose which views we need to create for the material.

Select Basic Data 1 Select Sales Org Data 1. You can always

extend the material master data later if you forgot to choose all needed views.

Select the Check Mark. You can see an option button marked in blue on the screen below for selecting all views (rarely used in a productive environment).

Step 3) In the next screen Enter Organizational levels for the

views we selected in the previous step.For example, those could be Plant, Storage Location, Sales Organization and Distribution Channel etc.

Click the Check Button

Process to Change Material Master Data

Step 1) Enter transaction code MMO2 in the

command prompt Enter the material number whose material

master data we want to change.Step 2) The next step is choosing the views for

which data is to be changed. For example, we will choose sales organization data 2 view.

You can choose one or more organizational levels for change.

Click on Organizational Levels Organizational level selectionStep 3) Maker the desired changes. Click the check button.

Step 4) After you have made the changes , you can check the changes in the corresponding view

Step 5) Click the save button , to save the changes NOTE:You can use transaction MM03 to display Material Master Data. In MM03, we can only display data without the possibility to change it (fields are greyed out).

Mass Creation of Material Master Data

In order to create multiple materials at once, you should have access to a function like

eCatt tool LSMW(Legacy System Migration

Workbench) BDC (Batch Data Communication)

recordings BAPI (Business Application Programing

Interface)

You can use MM17 for mass changing of material master data (if something can't be accomplished by this transaction it can be done using LSMW, BDC or BAPI). 

Step 1) Enter transaction MM17 Select the data type you need to change,

for example, we need to change a field in general data.

Execute.

Step 2) Enter the material range or list for which we

want to change the data ExecuteStep 3) When clicking on the button shown below –

you will get the Select fields screen. Check the appropriate field (we are

changing base unit of measure for our two materials).

Click the arrow pointing to the left to add the selected field to the list of fields to be changed.

Click the OK button.Step 4)  Now we are presented with the next screen

where we can input our value to be transferred. Let's say we have maintained PAL – pallet as the base unit of measure for our TV sets of 24" and 32" and we need to change that to PCS – pieces.

Enter the value you want to copy in the box.

Click on the column heading. Select the button, to overwrite the old

values by "PCS". Execute.
