What is SAP Transaction OMKW?

SAP Transaction OMKW (Maintain Valuation Classes) is a transaction code used in SAP MM to define valuation classes. Valuation classes are used to categorize material types for valuation purposes, such as determining the general ledger (G/L) accounts and account determination keys associated with a material. With OMKW, you can easily maintain and assign valuation classes to different material types in your SAP system.

Step 1: Accessing SAP Transaction OMKW

To start using OMKW, 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 “Valuation Classes”.
6. Next, choose “Define Valuation Classes” to proceed to the OMKW transaction.

Step 2: Understanding OMKW Transaction Screen

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

• Valuation Class: This field displays the valuation class code, which uniquely identifies a valuation class.
• Valuation Class Name: Here, you can enter a descriptive name for the valuation class.
• Valuation Category: This field allows you to specify the valuation category for the valuation class. Valuation categories determine the G/L accounts and account determination keys associated with a material.
• Account Category Reference: In this field, you can enter the account category reference for the valuation class. The account category reference determines the account assignment category for a material.
• Account Modification: Here, you can specify the account modification value for the valuation class. Account modification values are used to differentiate between different accounting principles or valuation approaches.

Step 3: Maintaining Valuation Classes with OMKW

To maintain valuation classes using OMKW, follow these steps:

1. Start by entering the valuation class code in the “Valuation Class” field.
2. Next, provide a descriptive name for the valuation class in the “Valuation Class Name” field.
3. Choose the appropriate valuation category from the dropdown menu in the “Valuation Category” field.
4. Enter the account category reference in the “Account Category Reference” field, if applicable.
5. Specify the account modification value in the “Account Modification” field, if required.
6. Once you have entered all the necessary information, click on the “Save” button to save the valuation class.

Congratulations! You have successfully maintained a valuation class using SAP transaction OMKW.

Step 4: Exploring Additional Functionality

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

• Display Valuation Classes: Use OMKW to display existing valuation classes by entering the valuation class code or other relevant criteria. This allows you to review and analyze the valuation classes defined in your SAP system.
• Change Valuation Classes: OMKW also enables you to modify existing valuation classes. You can edit fields such as the valuation class name, valuation category, account category reference, or account modification. Simply enter the valuation class code and make the necessary changes.
• Assign Valuation Classes: OMKW allows you to assign valuation classes to material types. This ensures that the correct valuation class is automatically assigned to materials of a specific type during procurement or production processes.
