If there are settings in Aloha to restrict multiple comps on a single check, the POS will display the following error message: 'Redemption Failed'.
All Punchh redemptions will fail when any POS offer, such as Employee Discount, Student Discount etc. is present on the check.
For instance,
1. After adding items to the receipt, cashier added POS Discount titled "15% Off" when a Nurse shows their ID card.
2. Cashier asks the nurse if they use Rewards app. if not, they can download, sign up and get a free drink.
3. The nurse shows the redemption QR code for the Free Drink on Sign Up offer which cashier scans.
4. An error dialogue appears with "Redemption Failed".
The AlohaPunchh log will show:
2019-05-13 12:33:42,401 WARN AlohaPunchh: Comp can not be applied. Punchh Comp Max: 1 Total Comps on check: 1
In order to allow guests to use multiple discounts per check, they probably should go to that particular discount setup on Aloha and remove the limit there.
The brand can navigate to Maintenance > Payments > Comps in Aloha and select the discount that needs to be modified. Verify the restrictions on the discounts they intend to combine with Punchh discount.
