SAP B1 Troubleshooting – Select HSN in line 1, since GST tax code is selected

Understanding and Resolving HSN Code Issues in SAP Business One

As SAP Business One consultants, we frequently encounter user queries about error messages that interrupt day-to-day transactions. One such issue arises when attempting to process marketing documents: “You must select HSN in line 1, since GST tax code is selected.”

In this blog, we’ll discuss the root cause of this error and provide a step-by-step solution to resolve it effectively.

Error Description

This error occurs during a marketing document transaction (e.g., sales order or invoice). When attempting to add the document, the system displays the following message:
“You must select HSN in line 1, since GST tax code is selected.”

Root Cause

The error is caused by the absence of an HSN Code in the GST details of the Item Master Data for the specific line item mentioned in the error message. The system mandates an HSN Code when a GST tax code is selected for a transaction.

Solution

Follow the steps below to resolve this issue:

1. Open the Item Master Data window for the item specified in the error message.
2. Navigate to the GST Details tab.
3. Check if the HSN Code is missing for the item.
   • If missing, enter the appropriate HSN Code in the field provided.

• Save your changes to update the Item Master Data.
• Return to the marketing document where the error occurred.
• Delete the row containing the affected item and re-add it to the document.

Attempt to post the document again. This time, it should post successfully without errors.

By ensuring that the HSN Code is updated in the Item Master Data, you can resolve the error and proceed with your transactions smoothly. Always validate the GST-related details of your items to prevent such errors in future transactions.
