Tutorial: How to Identify and Correct Blank HSN Code Entries in Logic ERP
In this tutorial, we’ll learn how to identify and correct blank HSN code entries to ensure your GST return is accurate and error-free.
Open the GST Returns Module
Navigate to the GST Returns module.
Select the desired GST return type (e.g., GSTR-1, GSTR-3B, etc.).
Choose the time period for which you want to generate the return.
Click on the Generate button.

Identify Blank HSN Code Entries
Click on the HSN column to view the detailed HSN data.
As shown, any blank HSN column indicates that the corresponding item was transacted without an assigned HSN code in the Item Master.

Note: Submitting a GST return with missing or incomplete HSN codes may result in rejection or incomplete filing.
Open the HSN Allocation Module
Navigate to the Setup\Setup Items and then select "Allocate Items to Harmonious Codes/Descriptions".
Click on Select Items to open the item selection window.
Open the HSN Code Filter dropdown and choose Nil to filter only the items that do not have an assigned HSN code.

Click Search — all items without HSN codes will be listed.
Assign the Correct HSN Code
Select the item with the blank HSN code and click OK.
Click on Refresh to load the selected item.

To allocate a new HSN code, press the Spacebar to open the HSN Code Search Window.
Note: If you want to change multiple HSN codes, press F2, and make sure the Overwrite HSN Code option at the top is ticked.
From the list, select the correct HSN code corresponding to the product.

Click Save to update the details.
Verify in GST Return
Return to the GST Returns module.
Regenerate the GST return for the same period.
Check the HSN column again — the previously blank field now displays the correct HSN code, confirming that the issue has been successfully resolved.

Your GST return is now complete and ready for submission without any missing HSN code entries.
