***

### Observe the Default Behavior

* Keep the **Lot Code Pre-Fix** option unconfigured.
* Navigate to the barcode printing section for **Purchase Vouchers**.
* Select the required Purchase Voucher.
* Select the required item.
* Click on **Create**.
* The **Barcode Printing Design Selection** window will appear.
* Click **No** to open the barcode design window.

**Result**

As no lot code prefix has been configured, the barcode label displays the **original lot code without any prefix**.

***

### Configure the Lot Code Prefix

* Return to the **Barcode Label Printing Configuration**.
* Locate the **"Lot Code Pre-Fix"** option.
* Select the required prefix from the dropdown list.
* Save the configuration changes.

#### Verify the Updated Lot Code

* Return to the barcode label printing window.
* Select the same **Purchase Voucher**.
* Select the required item.
* Open the barcode design.

**Result**

* The configured prefix is now automatically added to the lot code displayed on the barcode label.
* For example:&#x20;
  * **Original Lot Code:** `LOT001`
  * **With Prefix:** `PREFIX-LOT001`

***

### Key Benefits

* **Standardized Lot Codes:** Maintain a consistent lot code format across barcode labels.
* **Easy Identification:** Prefixes make lot codes easier to identify.
* **Better Tracking:** Simplifies lot-wise inventory tracking.
* **Flexible Configuration:** Select the required prefix according to business requirements.
* **Automatic Application:** The prefix is added automatically during barcode label printing.

***

### Important Note

The configured **Lot Code Pre-Fix** is reflected on the barcode label during printing. If no prefix is configured, the original lot code is displayed without modification.

***

### Final Outcome

By configuring the **"Lot Code Pre-Fix"** option, Logic ERP automatically adds the selected prefix to the lot code displayed on barcode labels, providing a standardized and easily identifiable lot code format.
