Dear sir,
I entered credit note in 9B in GTR1 of Sep 2017(quarterly filing), I am getting error message as" invalid original invoice details. Original invoice cannot be tracked. Please enter correct invoice number and date"
Actually I verified the bill, it is correct and submitted by seller. I manually copy pasted from GTR2A/view/credit debit note table. Still getting same error.
