SAP Business One users often encounter issues while processing marketing documents, particularly with interstate transactions. One common error is:

Error Message:
“For interstate transactions (line 1) you must choose IGST.”

This guide provides a detailed understanding of the issue, its root cause, and the step-by-step solution to resolve it effectively.

Error Description

When processing a marketing document, such as a sales order or invoice, you may encounter the following error message:

“For interstate transactions (line 1) you must choose IGST.”

Root Cause

This error typically occurs due to a mismatch between the state specified in the “Ship To Address” of the document and the state assigned to the company in the warehouse location setup. As per GST norms in India:

• Transactions between two entities located in the same state require CGST and SGST tax codes.
• Transactions between two entities located in different states require IGST tax codes.

In this case, the system detects an interstate transaction but does not find an appropriate IGST tax code selected.

Solution

Follow these steps to resolve the issue:

1. Verify the Ship To Address
   • Open the document where the error occurred.
   • Confirm that the “Ship To Address” specifies the correct state.
2. Check Warehouse Location Setup
   • Navigate to Administration > Setup > Inventory > Warehouses.
   • Ensure that the state specified for the warehouse matches the company’s actual location.

Select an IGST Tax Code

• In the marketing document, select an appropriate IGST Tax Code for the transaction.
• Save the document.

Re-validate the Document

• Try adding the document again. If the correct IGST tax code is selected, the document should post successfully.

Final Notes

By ensuring that the ship-to address and warehouse location are correctly defined and that the appropriate IGST tax code is selected, users can seamlessly process interstate transactions in SAP Business One.
