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.

Step 1: Accessing SAP Transaction MMNR

To start using MMNR, follow these steps:

  1. Log in to your SAP system using your user ID and password.
  2. Launch the SAP Easy Access Menu.
  3. Navigate to the “Logistics” folder and expand it.
  4. Locate and click on the “Materials Management” folder.
  5. 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:

  1. 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.
    • Description: Provide a descriptive name for the material.
    • Base Unit of Measure: Specify the base unit of measure for the material, such as pieces, kilograms, or liters.
    • Material Group: Select the appropriate material group for the material.

  2. Move to the relevant tabs (Purchasing Data, Sales Data, Plant Data, etc.) and enter the necessary information for each section.
  3. Once you have entered all the necessary information, click on the “Save” button to create or update the material master record.

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:

  • Display Material Master Records: Use MMNR to display existing material master records by entering the material code and other relevant criteria. This allows you to review and access the details of materials already created.
  • Change Material Master Records: MMNR also enables you to modify existing material master records. You can edit fields such as description, purchasing details, or other relevant information. Simply enter the material code and make the necessary changes.
  • 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.
  • Deletion of Material Master Records: In case you need to remove a material from your system, MMNR allows you to delete material master records. However, please note that this action should be performed with caution, as it permanently removes the material and its associated data.
