What is SAP Transaction OMNV?

SAP Transaction OMNV (Material Types) is a key transaction code used in SAP MM to define and maintain number ranges for material types. It allows users to assign unique number ranges to different material types, ensuring that each material type has its own set of unique identifiers. With OMNV, you can efficiently manage the numbering system for materials, enabling smooth material creation and tracking.

Step 1: Accessing SAP Transaction OMNV

To start using OMNV, 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 “Number Ranges” to proceed to the OMNV transaction.

Step 2: Understanding OMNV Transaction Screen

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

• Material Types: This section displays a list of material types for which you can define number ranges. You can select a material type from the list or create a new one.
• Number Range Intervals: Here, you can define the number range intervals for each material type. Each interval represents a range of numbers that can be assigned to materials of a particular type.
• Number Range Status: This tab provides an overview of the current status of number ranges for each material type. It shows whether a number range is active, inactive, or not yet defined.
• Number Range Assignments: The number range assignments tab allows you to assign specific number ranges to material types. This ensures that each material type has its own unique set of identifiers.
• Number Range Objects: In this tab, you can define number range objects, which are used to group related number ranges. For example, you can create a number range object for material numbers and assign different number ranges to it.

Step 3: Defining Number Ranges with OMNV

To define number ranges for material types using OMNV, follow these steps:

1. Start by selecting a material type from the “Material Types” section or create a new material type by clicking on the “New Entries” button.
2. In the “Number Range Intervals” tab, click on the “New Entries” button to define a new number range interval.
3. Enter the following details for the number range interval:

   • From Number: Specify the starting number of the number range interval.
   • To Number: Specify the ending number of the number range interval.
   • Current Number: Enter the current number to be assigned to the next material created.

4. Click on the “Save” button to save the number range interval.
5. Next, go to the “Number Range Assignments” tab and click on the “New Entries” button.
6. In the “Object” field, select the number range object to which you want to assign the number range. If the desired number range object is not available, you can create a new one by clicking on the “New Entries” button.
7. Specify the material type and number range interval for the assignment.
8. Click on the “Save” button to save the number range assignment.

Congratulations! You have successfully defined number ranges for material types using SAP transaction OMNV.

Step 4: Exploring Additional Functionality

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

• Display Number Range Intervals: Use OMNV to display existing number range intervals for material types. This allows you to review and modify the intervals as needed.
• Change Number Range Assignments: OMNV enables you to modify existing number range assignments. You can change the assigned number range intervals for material types or assign different number ranges to material types.
• Number Range Object Maintenance: You can use OMNV to create and maintain number range objects. This allows you to group related number ranges and assign them to material types.
