Help with Sales Tax less Coupon calculation
I need to change my sales tax calculation. Currently, I'm using the "out of the box" calculation, but it isn't reflecting the coupons we offer. The caculation I'm using is: Sum(Line Items::Taxable Amount) * Sales Tax Rate + If(Discount Rate;0;0). I've added an additional line on my invoices to deduct coupons, but sales tax is still being charged on the coupon amount. I need to deduct the coupon amount in the calculation in order for the tax to calculate correctly. Any suggestions? Thank you.
