What is SAP Transaction OMNB?

SAP Transaction OMNB (Price Change: Materials) is a transaction code used in SAP MM to perform price changes for materials. It allows users to update the prices of materials based on various factors such as vendor prices, exchange rates, and cost changes. With OMNB, you can easily manage and track price changes, ensuring accurate costing and pricing in your organization.

Step 1: Accessing SAP Transaction OMNB

To start using OMNB, 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 “Price Change.”
6. Click on “Materials” to proceed to the OMNB transaction.

Step 2: Understanding OMNB Transaction Screen

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

• Selection Criteria: This section allows you to define the parameters for selecting the materials for price change, such as material group, material type, and plant.
• Price Change Data: Here, you can enter the new prices for the selected materials. You can specify the price type (e.g., standard price, moving average price) and the effective date for the price change.
• Price Source: This tab enables you to choose the source for the new prices, such as vendor prices, exchange rates, or cost changes.
• Simulation: The simulation tab allows you to simulate the price change before actually executing it. This helps you verify the impact of price changes on costing and pricing.
• Execution: Once you have reviewed and confirmed the price change, you can execute it by clicking on the “Execute” button.

Step 3: Performing Price Change with OMNB

Performing a price change using OMNB involves the following steps:

1. Start by defining the selection criteria in the “Selection Criteria” section. You can specify the materials you want to change based on various parameters.
2. Move to the “Price Change Data” tab and enter the new prices for the selected materials. You can choose the price type (e.g., standard price, moving average price) and the effective date for the price change.
3. If necessary, go to the “Price Source” tab and select the appropriate source for the new prices, such as vendor prices or exchange rates.
4. Once you have reviewed all the information, click on the “Simulation” tab to simulate the price change. This will show you the impact of the price change on costing and pricing.
5. If you are satisfied with the simulation results, go to the “Execution” tab and click on the “Execute” button to perform the actual price change.

Congratulations! You have successfully performed a price change using SAP transaction OMNB.

Step 4: Exploring Additional Functionality

SAP transaction OMNB offers various additional functionalities to streamline your price change processes. Here are some notable features you can leverage:

• Mass Price Changes: OMNB allows you to perform mass price changes for a group of materials. Instead of changing prices individually, you can select multiple materials and update their prices simultaneously.
• Price History: OMNB provides access to the price history of materials, allowing you to track and analyze past price changes. This helps in making informed decisions regarding pricing and costing.
• Price Simulation: Before executing a price change, you can use the simulation feature to assess the impact of the price change on costing and pricing. This helps in identifying any potential issues or discrepancies.
• Variance Analysis: OMNB enables you to perform variance analysis by comparing the new prices with the old prices. This helps in identifying and addressing any significant deviations or discrepancies.
