What is SAP Transaction OMMZ?

SAP Transaction OMMZ (Material Type Number Range Intervals) is a transaction code used in SAP MM to define and manage the number range intervals for material types. It allows users to specify the range of numbers that can be assigned to different material types, ensuring proper organization and control of material numbers in the system.

Step 1: Accessing SAP Transaction OMMZ

To start using OMMZ, 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 click on “Number Range” to proceed to the OMMZ transaction.

Step 2: Understanding OMMZ Transaction Screen

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

• Material Type: In this field, you can enter or select the material type for which you want to define or manage the number range intervals.
• Number Range Interval: This section displays the existing number range intervals for the selected material type. It includes the range start and end values, as well as the current number.
• Create New Interval: By clicking on this button, you can create a new number range interval for the material type.
• Delete Interval: This button allows you to delete a selected number range interval for the material type.
• Save/Cancel: These buttons are used to save any changes made or to cancel the transaction without saving.

Step 3: Defining Number Range Intervals

To define number range intervals for a material type using OMMZ, follow these steps:

1. Enter or select the desired material type in the “Material Type” field.
2. Review the existing number range intervals for the material type in the “Number Range Interval” section.
3. To create a new interval, click on the “Create New Interval” button.
4. Specify the range start and end values for the new interval.
5. Click on the “Save” button to save the new interval.

Congratulations! You have successfully defined a new number range interval for a material type using SAP transaction OMMZ.

Step 4: Managing Number Range Intervals

In addition to defining number range intervals, OMMZ also allows you to manage existing intervals. Here are some common tasks you can perform:

• Edit Interval: To modify an existing number range interval, select the interval from the “Number Range Interval” section and click on the “Create New Interval” button. Make the necessary changes and save them.
• Delete Interval: If you want to delete a number range interval, select the interval from the “Number Range Interval” section and click on the “Delete Interval” button. Confirm the deletion when prompted.
• Review Interval Assignments: You can use the “Number Range Intervals” tab in the material type configuration to review the assignments of number range intervals to material types.
• Customize Number Range Intervals: OMMZ allows you to customize the number range intervals based on your organization’s requirements. You can define specific ranges for different material types, ensuring optimal organization and control of material numbers.
