How to Create Material Master in SAP MM

When we want to use a new material in SAP MM process which is important master data maintenance, we have to define it’s characteristics, in order to control it’s behavior in all of the transactions. Every material is created in the either of these two ways:

1. By calling transaction MM01 (mostly used in a productive environment)
2. 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) Initial Screen of SAP MM Material Master Data (MM01)

Transaction that is used for the creation of material master record, as stated above isMM01. The execution of the transaction brings us to the initial screen, which consists of few fields that contain the basic information on our material.

How to Change Material Master Data in SAP MM

It may be needed to change certain option in our material master (due to the organizational changes, or changes in processes). We cannot use MM01 as that is the transaction code used only for creating views that are not maintained for certain material. In this case, we need to use MM02 and MM03 transaction codes.

In SAP transactions ending with 01 are for creating, ending with 02 for editing/changing, and the ones ending in 03 are used for viewing data without possibility to change it.

Process to change Material Master in SAP MM

Step 1)

1. Enter transaction code MMO2 in the command prompt
2. Enter the material number whose material master data we want to change.

How to Create Multiple Material Master Data in SAP MM

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

1. eCatt tool
2. LSMW(Legacy System Migration Workbench)
3. BDC (Batch Data Communication) recordings
4. BAPI (Business Application Programing Interface)

You can also use mass maintenance transaction MM17 to create views in some cases.

But you must keep in mind that not all of the organizational levels should contain the same data (MM17 requires that all data for the materials and organizational levels you select should be the same).

Mass creation is never considered to be end users responsibility.But as a module specialist you may need to work on MM17 . In case of LSMW, BDC or BAPI, it is considered to be developers or consultants work. So you do not have to understand in detail, you just have to know the concept, and that there is this kind of possibility for mass data maintenance.

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)

1. Enter transaction MM17
2. Select the data type you need to change, for example, we need to change a field in general data.
3. Execute.
