In Oracle Simphony 19.5.4, I want to prevent users from being able to navigate to the Payments page if the combo meal is incomplete. In RES 3700, when you started selecting or assembling a combo meal, if you tried to navigate to the next page before completing the selection of Required Sides, it would indicate that you had not completed assembling the combo meal. Currently, I have not found a way to do this in Simphony, and it is causing problems because I have a payment method that uses an ISL (Invoice of Service) to charge a credit card via a PIN pad. After charging the card, it indicates that there are problems with the combo meal, and the order remains open (the transaction has already been charged, so I need to close it with another payment method, causing discrepancies). At Workaround, they recommended applying a Service Total Tender Media to the payment button as a Send and Stay. It works, and if the combo is incomplete, it indicates so. The problem is that the order immediately goes to the kitchen screens, and I usually only use the fire-on tender.

Any ideas?
