What is SAP Transaction MM02?

SAP Transaction MM02 (Change Material Master) is a key transaction code used in SAP MM to create, modify, and display material master data. Material master data contains detailed information about a material, such as its description, unit of measure, stock availability, and procurement details. With MM02, you can efficiently manage and maintain accurate material master data, ensuring smooth procurement and inventory management processes.

Step 1: Accessing SAP Transaction MM02

To start using MM02, 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 click on “Material” to proceed to the MM02 transaction.

Step 2: Understanding MM02 Transaction Screen

Once you have accessed MM02, you will encounter the MM02 transaction screen, which consists of various tabs and fields. Let’s explore each of them:

  • Basic Data 1: This tab contains essential information about the material, such as its description, base unit of measure, and material type. You can modify these fields as per your requirements.
  • Basic Data 2: Here, you can enter additional details about the material, such as its weight, volume, and dimensions. These details are crucial for accurate inventory management and procurement processes.
  • Purchasing: The purchasing tab allows you to define various purchasing-related parameters for the material, such as the purchasing group, valuation class, and procurement type.
  • Sales: In this tab, you can configure sales-related information for the material, such as sales organization, distribution channel, and pricing details. These details are necessary for seamless order processing and customer management.
  • Plant Data/Stor. 1: Here, you can define plant-specific data for the material, such as storage location, storage conditions, and availability check settings. These details ensure efficient inventory management and accurate stock availability checks.
  • Accounting: The accounting tab allows you to configure accounting-related settings for the material, such as general ledger (G/L) accounts and cost center assignments. These settings ensure accurate financial reporting and cost control.
  • MRP 1: In this tab, you can define material requirements planning (MRP) parameters for the material, such as the reorder point, safety stock, and planning horizon. These parameters help in maintaining optimal inventory levels and avoiding stockouts.
  • Additional Data: Here, you can enter any additional custom fields specific to your organization’s requirements. These fields provide flexibility and customization options for material master data.

Step 3: Modifying Material Master Data with MM02

To modify material master data using MM02, follow these steps:

  1. Start by selecting the appropriate material for modification in the “Material” field.
  2. Navigate through the tabs and modify the necessary fields as per your requirements. For example, you can update the material description, change the base unit of measure, or adjust the purchasing parameters.
  3. Once you have made the necessary changes, click on the “Save” button to save the modified material master data.

Congratulations! You have successfully modified material master data using SAP transaction MM02.
