What is SAP Transaction OML4?

SAP Transaction OML4 (Change Material Price) is a transaction code used in SAP MM to manage price changes for materials. It allows users to adjust the standard price, moving average price, and other valuation data for materials in their SAP system. With OML4, you can easily update material prices and ensure accurate cost calculations for inventory management and financial reporting purposes.

Step 1: Accessing SAP Transaction OML4

To start using OML4, 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 click on “Price Changes” to proceed to the OML4 transaction.

Step 2: Understanding OML4 Transaction Screen

Once you have accessed OML4, you will encounter the OML4 transaction screen, which consists of various fields and tabs. Let’s explore each of them:

• Selection Criteria: This section allows you to specify the materials for which you want to make price changes. You can choose to update prices for a specific material group, plant, or material type.
• Price Change Data: Here, you can enter the new prices and effective dates for the selected materials. You can choose to update the standard price, moving average price, or both.
• Price Change Simulation: This tab provides a simulation of the price changes before actually updating the prices in the system. It allows you to review the impact of the changes and make adjustments if necessary.
• Price Change Log: The log tab displays a record of all price change transactions performed using OML4. It includes details such as the material, old price, new price, and user who made the change.

Step 3: Performing Price Changes with OML4

To make price changes using OML4, follow these steps:

1. In the “Selection Criteria” section, specify the materials for which you want to make price changes. You can use various criteria such as material group, plant, or material type to narrow down the selection.
2. Move to the “Price Change Data” tab and enter the new prices and effective dates for the selected materials. You can choose to update the standard price, moving average price, or both.
3. Click on the “Simulate” button to review the impact of the price changes. The simulation will show you the updated material prices and any potential differences in inventory valuation.
4. If you are satisfied with the simulation results, click on the “Execute” button to update the prices in the system. A confirmation message will be displayed once the price changes are successfully made.

Congratulations! You have successfully performed price changes using SAP transaction OML4.

Step 4: Exploring Additional Functionality

SAP transaction OML4 offers additional functionalities to enhance your price management processes. Here are some notable features:

• Multiple Price Changes: OML4 allows you to make price changes for multiple materials at once. You can use the selection criteria to specify a group of materials and update their prices simultaneously.
• Mass Price Change Upload: If you have a large number of price changes to make, OML4 supports mass price change upload. You can prepare a spreadsheet with the new prices and effective dates, and then upload it directly into the system.
• Price Change Authorization: OML4 allows you to define authorization levels for price changes. This ensures that only authorized users can make price changes and prevents unauthorized modifications to material prices.
