## How to Change HSN Code for Items While Creating a Sale Bill?
In this tutorial, we’ll learn how to **edit or modify the HSN code** while creating a sales bill in Logic ERP.
***
### Edit HSN Code During Sales Bill Creation
* Generate a **Sales Bill**.
* In the **Item Search List**, you can see the HSN code of the selected item (for example, `62`).
* To edit, press **F4** on the selected item.
* The **Harmonious Search List** window will open → modify the HSN code as needed.
The modification will be applied instantly.
***
### Verify HSN Code in Item Setup
* Go to **Setup → Item Multiple Pack Sizes**.
* Check the HSN code of the respective item.
* You’ll see the updated code has been successfully applied.
***
### Allocate HSN Codes to Multiple Items
Logic ERP also provides a feature to **allocate HSN codes to multiple items** simultaneously. This can be done in two ways:
#### Method 1: Manual Allocation
* Navigate to: Setup\Setup Items and then select **"Allocate Items to Harmonious Codes/Descriptions".**
* Select the items for which you want to update the HSN code.
* Click **Refresh** and choose **Overwrite Existing**.
* Select the **HSN Serial Number**, press **F2**, and choose the desired HSN code.
* A confirmation window will appear → click **Yes** to apply the code to all selected items.
* The HSN code is now updated successfully.
***
#### Method 2: Allocation via Excel
* First, check the current HSN code of the item (e.g., `610462`).
* Go to the **Excel Help Option** to see the required column format.
* Create an Excel sheet with the updated HSN codes.
* In the allocation window, select **Retrieve from Excel**.
* Choose **Overwrite Existing**, then browse and upload the Excel file.
* Click **Refresh** → the HSN field will now display the updated value.
* Save the data.
The new HSN codes are successfully allocated to the respective items.
