5. Multiple Discount’s per Transaction
On Version 3 if a Sub-Total Discount was made the Terminal would automatically carry out
a Sub-Total and take the user into the Payment Screen if clear was pressed the ST Discount
would be reversed. The New Version 4 now allows Multiple Discounts. When a ST Discount
is made the Terminal does not automatically carry out a Sub-Total, it stays in the trading
screen displaying the discount amount. N.B If two or more different Levels of VAT are being
used, the discount for each VAT rate will be displayed. If it is a requirement to enter the
subtotal screen after the discount operation  add ,F5 to the end of the Discount Macro. As the
items appear on the Operator screen they can be voided if an error is made.
