GST will be applicable on return bill in inclusive mode for the bill items which were charged extra tax in VAT regime

Module:

POS - Normal POS
POS - POS as Collection Centre 

Reported Version:

 1.124.2

Scenario:

Every time a customer returns an item to any POS, a credit note is generated equal in value to the Net amount paid by the customer at the time of the sale. The formula for the Net amount where tax is excluded is as following:

Net Amount = (Basic Price - Discount) + tax.

GST slabs are determined on the basic price while the calculation are done on the taxable amount and GST rates are higher than the VAT rates. In some cases, it was found that on return of pre-GST items during the GST regime, customers would get a credit note of higher value than the Net amount of their POS bill.
