Dear Experts,
 
For the Invoice of Nov-2018 we have issued an Debit Note in Feb-2019. now the consignment is returned (sales Returns). The customer is denied to Pay for the Debit note since it was raised for the Freight Charges on the original Consignment. 
 
Now we have raised an Credit note to Customer for the Debit note issued earlier.
In GSTR-1 while uploading the Credit & Debit Note it is not accepting the Original Invoice Number ( Debit note-Number) .
 
 If we Mention the Nov-2018 Invoice , it will be time barred-because We can issue only up to Sep-of the Assessment year . i.e. in our case this credit note have been issued by Sep-2019.
 
Please suggest on this issue. Your valuable feedback is awaited.
 
Thanks & regards,
