What is SAP Transaction OMM5?

SAP Transaction OMM5 (Material Master Records: Conversion) is a transaction code used in SAP MM to convert material master records from one data format to another. It allows users to define conversion rules and execute the conversion process, ensuring a smooth transition of material master data when migrating to a new system or implementing changes in data structure.

Step 1: Accessing SAP Transaction OMM5

To start using OMM5, 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 “Material Master” and then choose “Tools”.
6. Next, click on “Material Master Records: Conversion” to access the OMM5 transaction.

Step 2: Understanding OMM5 Transaction Screen

Once you have accessed OMM5, you will encounter the OMM5 transaction screen, which consists of various fields and tabs. Let’s explore each of them:

• Selection Criteria: This section allows you to specify the selection criteria for the material master records you want to convert. You can define filters based on material numbers, material types, plant codes, and other relevant attributes.
• Conversion Rules: Here, you can define the conversion rules for transforming your material master data. You can map fields from the source data format to the target format, specify data transformations, and handle any data validation or cleansing requirements.
• Conversion Log: This tab provides a log of the conversion process, showing any errors or warnings encountered during the conversion. It allows you to review and analyze the results of the conversion.
• Execution: In this tab, you can execute the conversion process based on the defined selection criteria and conversion rules. The system will process the selected material master records and apply the specified transformations.

Step 3: Performing Material Master Records Conversion with OMM5

To perform a material master records conversion using OMM5, follow these steps:

1. Start by specifying the selection criteria in the “Selection Criteria” section. You can choose to convert all material master records or apply filters to select specific records based on your requirements.
2. Move to the “Conversion Rules” tab and define the conversion rules for transforming your material master data. You can map fields from the source format to the target format, apply data transformations, and handle any data validation or cleansing requirements.
3. Once you have defined the selection criteria and conversion rules, click on the “Execute” tab to start the conversion process.
4. Review the conversion log in the “Conversion Log” tab to check for any errors or warnings encountered during the conversion process.
5. After reviewing the conversion log, you can save the log for future reference or make any necessary adjustments to the conversion rules and re-execute the process if needed.

Congratulations! You have successfully performed a material master records conversion using SAP transaction OMM5.

Step 4: Exploring Additional Functionality

SAP transaction OMM5 offers various additional functionalities to streamline your material master data management processes. Here are some notable features you can leverage:

• Mass Conversion: OMM5 allows you to convert multiple material master records at once, saving time and effort. You can define selection criteria to choose the records you want to convert and apply the conversion rules to all selected records simultaneously.
• Data Validation: OMM5 provides options to validate the converted data, ensuring its accuracy and consistency. You can define validation rules to check the integrity of the converted data and identify any errors or inconsistencies.
• Error Handling: In case of any errors or warnings encountered during the conversion process, OMM5 allows you to handle them efficiently. You can review the conversion log, identify the issues, and take appropriate actions to rectify the errors or warnings.
• Simulation Mode: OMM5 offers a simulation mode that allows you to test the conversion process without actually modifying the material master records. This enables you to validate the conversion rules and ensure their effectiveness before executing the actual conversion.
