What is SAP Transaction OMNT?

SAP Transaction OMNT (Material Master Data Maintenance) is a critical transaction code used in SAP MM to create, change, and display material master data. Material master data contains essential information about materials, such as their description, attributes, and classification. With OMNT, you can efficiently manage and update material master records, ensuring accurate and up-to-date information for your organization.

Step 1: Accessing SAP Transaction OMNT

To start using OMNT, 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 OMNT transaction.

Step 2: Understanding OMNT Transaction Screen

Once you have accessed OMNT, you will encounter the OMNT 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 material type, base unit of measure, and industry sector.
• Organization Data: Here, you can maintain data related to the organizational structure, such as the plant and storage location where the material is stored.
• Purchasing Data: This tab allows you to manage purchasing-related information for the material, such as the purchasing group, purchasing organization, and vendor details.
• Sales Data: If the material is relevant to sales processes, you can maintain sales-related data in this tab, including sales organization, distribution channel, and pricing conditions.
• Accounting Data: The accounting tab displays accounting-related information, such as the general ledger (G/L) accounts and cost centers associated with the material.
• Classification Data: In this tab, you can assign classification values to the material based on specific characteristics and classes.
• Additional Data: Here, you can maintain additional data for the material, such as weight, volume, and dimensions.

Step 3: Creating a New Material Master Record

To create a new material master record using OMNT, follow these steps:

1. Start by filling in the necessary fields in the “General Data” section:

   • Material Type: Select the appropriate material type for the material you are creating.
   • Base Unit of Measure: Specify the base unit of measure for the material.
   • Industry Sector: Choose the industry sector that best represents the material.

2. Move to the relevant tabs (Organization Data, Purchasing Data, Sales Data, etc.) and enter the required information for each tab based on your organization’s needs.
3. Once you have entered all the necessary data, click on the “Save” button to create the material master record.

Congratulations! You have successfully created a new material master record using SAP transaction OMNT.

Step 4: Changing and Displaying Material Master Data

In addition to creating new material master records, OMNT also allows you to change and display existing material master data. Here’s how:

• To change material master data, enter the material number you want to modify in the “Material” field on the OMNT transaction screen. Make the necessary changes in the relevant tabs and click on the “Save” button to update the material master data.
• To display material master data, enter the material number you want to view in the “Material” field on the OMNT transaction screen. The system will display the existing material master data, allowing you to review the information.
