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.

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.
