Effective Date of the Amendment is not specified or invalid
Cause
When you alter a transaction after signing the Return, it becomes an Amendment invoice, which cannot be added in the current period. However, you can move it to the subsequent return period. So, you will need to provide the effective date for amendment of the invoice in the subsequent period.
Resolution
- Open the GSTR-1 report, drill down from Uncertain Transactions.
- Press Enter on Date of the Amendment is not specified or invalid.
- Press Alt+L (Set Effective Date).
- Enter a date of the subsequent return period.
When you open the Return report for the subsequent period, you will find the transaction under Amendment B2B Invoices – 9A.
