Now, let’s begin our tutorial on using SAP transaction OMNJ.

What is SAP Transaction OMNJ?

SAP Transaction OMNJ (Price Determination for Material Cost Estimates) is a transaction code used in SAP MM to configure and maintain price determination settings for material cost estimates. It allows users to define and manage various factors that influence the calculation of material costs, such as overhead rates, cost components, and costing variants. With OMNJ, you can ensure accurate and consistent material cost estimates, enabling effective cost control and decision-making.

Step 1: Accessing SAP Transaction OMNJ

To start using OMNJ, 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 “Material Costing” to access the OMNJ transaction.

Step 2: Understanding OMNJ Transaction Screen

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

• Costing Variant: This field allows you to select the costing variant, which determines the rules and methods used for material cost estimation.
• Overhead: In this tab, you can define and maintain overhead rates that contribute to the overall material costs. Overhead rates represent indirect costs, such as utilities, rent, and depreciation.
• Cost Component Structure: Here, you can configure and manage the cost components that make up the total material costs. Cost components represent different types of costs, such as raw material costs, labor costs, and transportation costs.
• Price Update: The price update tab allows you to update material prices based on cost estimates. You can specify the conditions and criteria for price updates, such as frequency and valuation strategy.
• Other Settings: In this tab, you can define additional settings related to material cost estimation, such as currency conversion factors, profit margins, and rounding rules.

Step 3: Configuring Material Cost Estimation with OMNJ

To configure material cost estimation using OMNJ, follow these steps:

1. Select the appropriate costing variant from the “Costing Variant” field.
2. Click on the “Overhead” tab to define and maintain overhead rates. Enter the necessary details, such as overhead type, rate, and validity period.
3. Move to the “Cost Component Structure” tab and configure the cost components that make up the material costs. Specify the cost component type, description, and percentage.
4. Proceed to the “Price Update” tab and define the conditions for updating material prices based on cost estimates. Set the update frequency, valuation strategy, and other relevant parameters.
5. If needed, navigate to the “Other Settings” tab and configure additional settings, such as currency conversion factors, profit margins, and rounding rules.
6. Once you have configured all the necessary settings, click on the “Save” button to save your changes.

Congratulations! You have successfully configured material cost estimation using SAP transaction OMNJ.

Step 4: Exploring Additional Functionality

SAP transaction OMNJ offers various additional functionalities to enhance your material cost estimation processes. Here are some notable features you can leverage:

• Price Determination Analysis: OMNJ allows you to analyze and evaluate the results of material cost estimation. You can review cost estimates, compare different scenarios, and identify cost-saving opportunities.
• Costing Variants: You can create and maintain multiple costing variants in OMNJ, each with its own set of rules and methods for material cost estimation. This flexibility allows you to tailor the cost estimation process to different material types and scenarios.
• Simulation Mode: OMNJ provides a simulation mode that allows you to perform “what-if” analysis and test the impact of different cost estimation parameters. This feature helps you evaluate the potential outcomes of cost estimation before making any changes.
• Integration with Other SAP Modules: OMNJ seamlessly integrates with other SAP modules, such as Production Planning (PP) and Controlling (CO), enabling comprehensive cost control and analysis across the entire supply chain.
