Our sales tax changed from 6% to 7%, and I changed the sales tax appropriately. The item tax is set up with this 7% sales tax. I then added another sales tax, 6%, to be used for returns on sales rung up with 6% sales tax.
At POS when recalling an old sale, I enter Shift-F12 Taxes and select the 6% sales tax. But all this does is zero out the sales tax. Any idea why this happens or is there something in configuration that is causing this?
