What is SAP Transaction OMLC?

SAP Transaction OMLC (Define Tolerance Groups for Inventory Management) is a vital transaction code used in SAP Materials Management (MM) module to configure tolerance groups for inventory management. It allows users to define tolerance limits for various inventory-related activities, such as goods receipt, goods issue, and stock transfers. With OMLC, you can set up specific tolerances to monitor and control inventory movements, ensuring accurate inventory management and preventing errors.

Step 1: Accessing SAP Transaction OMLC

To start using OMLC, 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 “Inventory Management”.
6. Next, choose “Define Tolerance Groups” and click on “Define Tolerance Groups for Inventory Management” to proceed to the OMLC transaction.

Step 2: Configuring Tolerance Groups in OMLC

Once you have accessed OMLC, you will encounter the tolerance group configuration screen. This screen allows you to define tolerance limits for various inventory-related activities. Let’s explore how to configure tolerance groups in OMLC:

1. Start by selecting the appropriate tolerance group from the list or create a new one by clicking on the “New Entries” button.
2. In the tolerance group configuration screen, you will find various fields to define tolerance limits, such as:

   • Goods Receipt: Set the permissible deviation limits for goods receipt activities, such as quantity and value.
   • Goods Issue: Define the allowable variances for goods issue operations, including quantity and value.
   • Stock Transfers: Specify the tolerance limits for stock transfer activities, both within the same plant and between different plants.
   • Physical Inventory: Configure tolerance limits for physical inventory counts, ensuring accuracy in stock taking.

3. Enter the desired tolerance limits for each activity based on your organization’s requirements.
4. Once you have configured the tolerance group, click on the “Save” button to save the changes.

Congratulations! You have successfully configured tolerance groups for inventory management using SAP transaction OMLC.

Step 3: Testing Tolerance Group Settings

After configuring tolerance groups in OMLC, it is essential to test the settings to ensure they are working as intended. Here’s how you can test the tolerance group settings:

1. Create a test scenario by performing an inventory-related activity, such as goods receipt, goods issue, or stock transfer.
2. Observe whether the system allows or restricts the activity based on the configured tolerance limits.
3. If the activity exceeds the defined tolerance limits, the system will issue a warning or error message, indicating the deviation from the set limits.
4. Make any necessary adjustments to the tolerance group settings in OMLC, if required, to align with your organization’s tolerance policy.
