## 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://kb.logicerp.com/logic-erp-learning-hub-tutorials-and-best-practices/user-access/logic-global-admin/others/other-settings/use-additional-item-codes-for-item-barcode-scanning-in-all-data-entry-documents.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
