Credit generated by Overpayment cannot be used or refunded

This can affect all orgs **This workflow can be prevented - see below Reported Issue: Invalid patient credit Tier II Investigation Notes: SF Case: 142914 OrgID: 200286 Domain: @creekview Client made a payment against an open balance. The payment was overpayment of $60 on a $30 balance. The invoice was balanced to $0 while the ledger reported a $30 credit. At this point the credit should be valid and usable or refundable, however no option for the credit to be refunded is available. Steps to reproduce are below, however this can't be done on boardwalk as it has a new payment window. **As per Tim: The new payment window (which would block this workflow from occurring) is enabled with the "Minimum Deposit" feature. When this feature is enabled and active for all orgs, this TFS can be removed. Expected: Overpayments made to an invoice allow the excess payment (credit generated) to be used or refunded on subsequent invoices or balances Actual: Overpayments can be made to an invoice balance, however the leftover credit generated by the overpayment cannot be interacted with. Steps: Create an invoice with a balance for patient Click 'Pay' and in the amount to pay change it to something higher than the balance due Complete payment and close invoice In ledger view patient credit in summary that is not attached to any invoice This credit cannot be refunded as there is no refund button The payment can be voided to return the ledger and invoice back to reflecting the balance correctly.
