What is SAP Transaction OML5?

SAP Transaction OML5 (Material Number Range) is a transaction code used in SAP MM to define and manage number ranges for material master data. It allows users to customize and control the assignment of material numbers, ensuring efficient management of materials within an organization. With OML5, you can easily configure material number ranges and ensure consistency across your material master data.

Step 1: Accessing SAP Transaction OML5

To start using OML5, follow these steps:

1. Login 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 click on “Material Number Range” to proceed to the OML5 transaction.

Step 2: Understanding OML5 Transaction Screen

Once you have accessed OML5, you will encounter the OML5 transaction screen, which consists of various fields and tabs. Let’s explore each of them:

• Material Type: This field allows you to select the material type for which you want to define or change the number range. Material types categorize materials based on their attributes and usage within your organization.
• Number Range: Here, you can view and configure the number range settings for the selected material type. The number range determines the range of valid material numbers that can be assigned to materials of the selected type.
• External Number Assignment: This field indicates whether the material numbers are assigned externally or internally. If set to “External”, you need to manually enter the material number during material creation. If set to “Internal”, the system automatically assigns the material number based on the defined number range.
• Interval: This tab displays the current intervals defined for the selected material type’s number range. Each interval represents a range of material numbers that can be assigned to materials of the selected type.
• External Number Ranges: In this tab, you can define external number ranges for specific material types. External number ranges allow you to assign material numbers from an external system or source.

Step 3: Defining or Changing Material Number Range with OML5

To define or change the material number range using OML5, follow these steps:

1. Select the desired material type for which you want to define or change the number range.
2. Click on the “Number Range” button to access the number range settings.
3. In the “Number Range” tab, you can view the current settings for the selected material type. To change the number range, click on the “Change Intervals” button.
4. In the “Change Intervals” screen, you can add, modify, or delete intervals based on your requirements. Specify the start and end values for each interval, and define the interval status as “Active” or “Inactive”.
5. If needed, switch to the “External Number Ranges” tab to define external number ranges for the selected material type.
6. Once you have made the necessary changes, click on the “Save” button to save the material number range settings.

Congratulations! You have successfully defined or changed the material number range using SAP transaction OML5.

Step 4: Exploring Additional Functionality

SAP transaction OML5 offers various additional functionalities to enhance your material master data management. Here are some notable features you can leverage:

• Display Material Number Ranges: Use OML5 to display the existing material number ranges for different material types. This allows you to review and ensure the consistency of material number assignments.
• Copy Number Ranges: OML5 enables you to copy number ranges from one material type to another. This feature saves time and effort in setting up similar number ranges for different material types.
• Number Range Status: OML5 allows you to activate or deactivate number ranges for specific material types. This feature is useful when you want to temporarily restrict the assignment of material numbers for certain material types.
