What is SAP Transaction OMNW?

SAP Transaction OMNW (Configure Valuation Areas) is a transaction code used in SAP MM to configure valuation areas and valuation methods. Valuation areas are organizational units within an organization where materials are valued. Valuation methods determine how the valuation of materials is performed. With OMNW, you can define and maintain valuation areas and methods, ensuring accurate material valuation and financial reporting.

Step 1: Accessing SAP Transaction OMNW

To start using OMNW, 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 “Valuation” and then choose “Configure Valuation Areas” to proceed to the OMNW transaction.

Step 2: Understanding OMNW Transaction Screen

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

• Valuation Areas: This section allows you to define and maintain valuation areas. Valuation areas are represented by a four-character code and can be assigned to plants or company codes.
• Valuation Methods: Here, you can configure and manage valuation methods. Valuation methods determine how the valuation of materials is performed, such as standard price, moving average price, or FIFO.
• Integration: The integration tab provides options to link valuation areas with other modules or processes, such as Financial Accounting (FI) or Sales and Distribution (SD).
• Customizing: In this tab, you can find additional settings and customizations specific to your organization’s requirements.
• Help: The help tab provides access to documentation and resources related to OMNW and valuation area configuration.

Step 3: Configuring Valuation Areas and Methods

Configuring valuation areas and methods in OMNW involves the following steps:

1. Start by defining valuation areas. Select the “Valuation Areas” section and click on the “New Entries” button to create a new valuation area. Enter the necessary details, such as the valuation area code, description, and assignment to a plant or company code.
2. Next, configure valuation methods. Go to the “Valuation Methods” section and click on the “New Entries” button to create a new valuation method. Specify the valuation method code, description, and other relevant parameters.
3. Once you have defined valuation areas and methods, you can assign valuation methods to valuation areas. In the “Valuation Areas” section, select the desired valuation area and click on the “Valuation Methods” button. Assign the appropriate valuation method(s) to the valuation area.
4. After configuring valuation areas and methods, save your changes by clicking on the “Save” button.

Congratulations! You have successfully configured valuation areas and methods using SAP transaction OMNW.

Step 4: Exploring Additional Functionality

SAP transaction OMNW offers various additional functionalities to streamline your material valuation processes. Here are some notable features you can leverage:

• Changing Valuation Area Settings: OMNW allows you to modify existing valuation areas and their settings. You can edit fields such as the description, assignment to plants or company codes, or integration with other modules.
• Updating Valuation Methods: You can also make changes to existing valuation methods, such as updating parameters or adding new valuation methods. OMNW provides flexibility in configuring valuation methods according to your organization’s requirements.
