What is SAP Transaction MMNR?
SAP Transaction MMNR (Material Master Record Maintenance) is a key transaction code used in SAP MM to create and maintain material master records. The material master record contains all the essential information about a material, such as its description, attributes, storage locations, and purchasing details. MMNR allows users to easily create, update, and manage material master records, ensuring accurate and efficient material management.

- From the sub-menu, select “Material Master” and then choose “Material” to proceed to the MMNR transaction.
Step 2: Understanding MMNR Transaction Screen
Once you have accessed MMNR, you will encounter the MMNR transaction screen, which consists of various fields and tabs. Let’s explore each of them:
- General Data: This section contains the main fields for entering general information about the material, such as its description, base unit of measure, and material group.
- Purchasing Data: Here, you can maintain purchasing-related information for the material, such as the purchasing group, purchasing organization, and valuation class.
- Sales Data: This tab allows you to enter sales-specific information for the material, including the sales organization, distribution channel, and division.
- Plant Data: In this section, you can define plant-specific details for the material, such as the storage location, valuation area, and accounting data.
- Storage Data: Here, you can maintain storage-related information for the material, including the storage conditions, hazardous material indicator, and storage bin data.
- Work Scheduling: This tab allows you to define work scheduling details for the material, such as the planned delivery time and goods receipt processing time.
- MRP Data: In this section, you can maintain material requirements planning (MRP) data for the material, including the MRP type, lot sizing procedure, and reorder point.
Step 3: Creating and Maintaining Material Master Records with MMNR
To create or maintain material master records using MMNR, follow these steps:
- Start by filling in the necessary fields in the “General Data” section:
- Material: Enter the material code or use the search function to find it.

Congratulations! You have successfully created or maintained a material master record using SAP transaction MMNR.
Step 4: Exploring Additional Functionality
SAP transaction MMNR offers various additional functionalities to streamline your material master record management processes. Here are some notable features you can leverage:

- Mass Maintenance: MMNR supports mass maintenance functionality, allowing you to update multiple material master records simultaneously. This feature is particularly useful when you need to make the same changes to a group of materials.
