While uploading Debit Note / Credit Note issued against invoices of Pre-GST regime either by using csv file or by excel workbook, GST Offline Tool (both Version 1.3 & 1.4) throws an error “Invalid inputs at row level”. This may be due to some technical bug in the GSTN system. Below mentioned is the possible way you can upload CN/DN against invoices pertaining to Pre-GST regime:
1. In case total CN/DN transaction count is less than 500: Upload CN/DN transactions flagged against Pre-GST invoices as “Y” manually online at the GSTN portal. For rest of the CN/DN transactions, csv file / excel workbook may be used to generate JSON file at the GST offline tool.
2. In case total CN/DN transaction count is more than 500: Upload CN/DN transactions flagged against Pre-GST invoices as “Y” manually at the GST offline tool (Do not use csv file / excel workbook to upload these transactions). Thereafter generate JSON and upload the same online at GSTN portal.
Use this method until the technical bug is cleared.
