What is SAP Transaction OMM4?
SAP Transaction OMM4 (Define Material Types) is a transaction code used in SAP MM to define and configure material types in the system. Material types are used to categorize materials based on their characteristics and behavior within the organization. With OMM4, you can easily customize and create new material types to meet your specific business requirements.

- From the sub-menu, select “Material Master” and click on “Material Types”.
- Next, choose “Define Attributes of Material Types” to proceed to the OMM4 transaction.
Step 2: Understanding OMM4 Transaction Screen
Once you have accessed OMM4, you will encounter the OMM4 transaction screen, which consists of various fields and tabs. Let’s explore each of them:
- Main Screen: This section displays the list of existing material types and their corresponding attributes.
- Material Type Details: Here, you can view and edit the attributes of a selected material type, such as the valuation class, account category reference, and other relevant settings.
- Additional Data: This tab provides additional fields and settings related to the selected material type, such as the default storage location, purchasing group, and planning data.
- Field Selection: The field selection tab allows you to customize the screen layout and define which fields are visible and editable for a particular material type.
- Classification: In this tab, you can assign classification values to the material type, such as industry sector, product hierarchy, or material group.
- Views: The views tab allows you to define and configure additional views for the material type, such as sales, purchasing, or production views, to capture specific information or attributes.
Step 3: Customizing Material Types with OMM4
To customize a material type using OMM4, follow these steps:
- Start by selecting a material type from the main screen or click on the “New Entries” button to create a new material type.
- In the Material Type Details tab, you can modify the attributes of the selected material type, such as the valuation class, account category reference, and other relevant settings.
- Move to the Additional Data tab and enter any additional fields or settings specific to the material type, such as the default storage location, purchasing group, or planning data.
- If needed, customize the screen layout and field selection in the Field Selection tab to define which fields are visible and editable for the material type.
- Assign classification values to the material type in the Classification tab, such as industry sector, product hierarchy, or material group.
- Finally, define and configure additional views for the material type in the Views tab, such as sales, purchasing, or production views, to capture specific information or attributes.
- Click on the “Save” button to save your changes and finalize the customization of the material type.
Congratulations! You have successfully customized a material type using SAP transaction OMM4.
Step 4: Exploring Additional Functionality
SAP transaction OMM4 offers various additional functionalities to further enhance your material management processes. Here are some notable features you can leverage:
- Copy Material Types: OMM4 allows you to copy existing material types to create new ones, saving time and effort in defining similar material types.
