Dear buddies,
I am working on coupon solution to RMS. Suppose a shopper purchases items of $100.00 in tatal, and the cashier scans coupons of $5.00, when the tender form is displayed, the $5.00 coupon is already filled in the coupon tender field by my add-in, so the balance becomes $95.00 on the tender form. However, the pole display still shows the total amount of $100.00. This is embarassing for shopper. I noticed that Transaction.Total property is read-only. How can I change the total amount to the balance on the pole display? Or how to show the balance on the pole display?
