Customer Refund Processing / Reconciliation

Hi everyone,

We have a lot of cases in our company that the customer pay in advance (Sales order > Down Payment> Incoming Payment > AR Invoice) and we need to refund them. We use outgoing payment to fix it but our reconciliation still is open, because when we try reconcile Outgoing payment with Incoming Payment (linked A/R Invoice) the system doesn't allow.

Someone have a suggestion to fix this issue because this process is recurrent in our company.

Thanks.

Leo
