"A" is manufacturer and supply goods to "X" on wholesale price less Pre-defined Trade Discount & Cash Discount at time of supply and reduces the same in the TAX INVOICE itself and charged GST on reduced value of goods.

"X" made payment of the Invoice on due dates.

Subsequently based on the total supply of goods, "A" issue Credit Notes towards Discount called as Quantity Discount/Incentives etc. without mentioning any GST on the said value and paid through Cheque/DD/RTGS/NEFT to "X" or even allowed "X" to deduct the value of Credit Notes from future payables.

My Question is :

What is the treatement of this Credit Note in the hands of "A" as well as in the hand of "X" under GST Act?
