When a gap claim benefit amount is processed, the customer pays the gap amount, and their account balance is adjusted using a Credit Adjustment to reflect the benefit amount.
This in inadequate from a reporting perspective, as credit adjustments affect total sales, and the benefit amount is not reflected in the practice income.
They need to be treated as a payment against the customer's account, as the payment will be made by the insurer.
To accurately reflect practice income, the Credit Adjustment needs to be replaced with a Payment containing a Payment Other record, with a Payment Type of Gap Payment.
As payments require a till, each practice location will need a 'Gap Payment Till'. If no till is configured, one will be prompted for.
