What is SAP Transaction OMN0?

SAP Transaction OMN0 (Material Master Records) is a transaction code used in SAP MM to create, change, and display material master records. Material master records contain important information about materials, such as their descriptions, attributes, and accounting data. OMN0 allows users to maintain accurate and up-to-date material master records, ensuring smooth operations within an organization.

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 OMN0 transaction.

Step 2: Understanding OMN0 Transaction Screen

Once you have accessed OMN0, you will encounter the OMN0 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 type.
• Purchasing: Here, you can maintain purchasing-related information for the material, such as its purchasing group, vendor, and purchasing organization.
• Sales: In this tab, you can enter sales-related data for the material, including sales organization, distribution channel, and division.
• Plant Data: The plant data tab allows you to specify the storage location, valuation class, and other plant-related information for the material.
• Accounting: In this tab, you can maintain accounting-related data for the material, such as the general ledger (G/L) accounts and cost centers associated with it.
• Quality Management: Here, you can define quality management-related settings for the material, such as inspection type and sampling procedure.
• Classification: The classification tab enables you to assign classification attributes to the material, allowing for easier categorization and searching.
• Additional Data: This tab contains additional fields where you can enter any custom or specific data for the material, based on your organization’s requirements.

Step 3: Creating Material Master Records with OMN0

To create material master records using OMN0, follow these steps:

1. In the “General Data” tab, enter the necessary information for the material, such as its description, base unit of measure, and material type.
2. Move to the relevant tabs (e.g., Purchasing, Sales, Plant Data) and enter the corresponding data for each section based on your organization’s requirements.
3. If needed, navigate to the “Additional Data” tab and fill in any custom fields or specific information for the material.
4. Once you have entered all the necessary information, click on the “Save” button to create the material master record.

Congratulations! You have successfully created a material master record using SAP transaction OMN0.
