I Have a requirement.
There is One PO and Have One Item.
Item Price = 100 and Quantity = 1
Then Gross Price will be 100 and then apply Discount 10
after Discount Price will be 90.
So, How Can I apply GST conditions based on after Discount Price like if After Discounted Price > 90 then apply 5% GST elseif After Discounted Price < 90 then apply 12% GST.
