## How to Enable Additional Item Codes for Barcode Scanning Across Data Entry Documents?
In this tutorial, we’ll cover how to enable a **Logic ERP** feature that allows barcode scanning using **both main item codes and additional item codes** in all data entry documents.
***
### Enable the Feature in Logic Admin
* Open **Logic Admin**.
* Navigate to **Global Settings.**
* Under the **Others** section click on **Other Setting**.
* Locate and enable the option labeled as:
> **“Use Additional Item Codes for Item Barcode Scanning in all Data Entry Documents”**
* Click **Save** and **restart** the software for the changes to take effect.
***
### **Understanding the Feature**
* **Default Behavior**: Barcode scanning uses the **main item code** during sales or purchase transactions.
* **Enhanced Behavior**: When this option is enabled, the system also recognizes **additional item codes** assigned to the same item.
* This is useful when:
* A product is sold under **different barcodes**.
* You maintain **branch-specific or vendor-specific codes**.
***
### Implement **the Feature**
* Start a **new transaction** (sales, purchase, or any item entry document).
* Scan the **main item code** → the item is added as usual.
* Scan an **additional item code** → the same item is added successfully.
***
### **Defining Additional Item Codes**
* Go to the **Setup Item** window.
* Search for the desired item.
* In the **Pack Details** section, find the field for **Additional Item Code**.
* Enter the code(s). You may define **multiple additional codes** for a single item.
* Save the item details.
***
### **Conclusion**
Enabling this option allows:
* **Flexible barcode scanning** for items with multiple identifiers.
* **Streamlined operations** when handling products with different codes from suppliers, manufacturers, or branches.
