What is SAP Transaction OBYR?

SAP Transaction OBYR (Maintain Tolerance Groups for Inventory Management) is a critical transaction code used in SAP MM to define tolerance groups for material movements. Tolerance groups allow you to set limits on certain key aspects, such as price differences, quantity differences, and value differences, for material movements. With OBYR, you can ensure that any material movements falling outside the defined tolerance limits require additional approvals or actions, enabling better control over inventory management.

Step 1: Accessing SAP Transaction OBYR

To begin using OBYR, 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 “Inventory Management”.
6. Select “Tolerance Groups” and click on “Maintain Tolerance Groups for Inventory Management” to proceed to the OBYR transaction.

Step 2: Understanding OBYR Transaction Screen

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

• General Data: This section contains the main fields for defining tolerance groups, such as the tolerance group key, description, and validity period.
• Tolerances: Here, you can set the tolerance limits for various material movements, such as goods receipts, goods issues, and stock transfers. You can define limits based on price differences, quantity differences, and value differences.
• Additional Data: This tab allows you to specify additional settings, such as whether the tolerance limits apply to goods movements with or without reference documents, and whether tolerances are checked during document entry or posting.
• Authorization: The authorization tab provides options to assign authorization groups to the tolerance groups, ensuring that only authorized personnel can make changes to the tolerance limits.

Step 3: Defining Tolerance Groups with OBYR

To define tolerance groups using OBYR, follow these steps:

1. In the “General Data” section, enter a unique tolerance group key and a meaningful description.
2. Specify the validity period for the tolerance group, indicating the start and end dates.
3. Move to the “Tolerances” tab and set the tolerance limits for the relevant material movements. For example, you can define a price difference tolerance of 5% for goods receipts. This means that any goods receipt with a price difference exceeding 5% will require additional approval or action.
4. In the “Additional Data” tab, configure the additional settings based on your organization’s requirements. For example, you can choose to check tolerances during document entry or posting, and whether to include goods movements without reference documents.
5. If necessary, assign an authorization group to the tolerance group in the “Authorization” tab to restrict access to authorized personnel.
6. Once you have defined all the necessary tolerance groups, click on the “Save” button to save your changes.

Congratulations! You have successfully defined tolerance groups using SAP transaction OBYR.

Step 4: Exploring Additional Functionality

SAP transaction OBYR offers additional functionalities to enhance your inventory management processes. Here are a few notable features:

• Display Tolerance Groups: Use OBYR to display existing tolerance groups by entering the tolerance group key. This allows you to review and analyze the defined tolerance limits.
• Change Tolerance Groups: OBYR allows you to modify existing tolerance groups. You can make changes to the tolerance limits, validity period, or additional settings as necessary.
• Assign Tolerance Groups: Assign tolerance groups to user roles or organizational units to ensure that the defined tolerance limits are applied during material movements.
