Hi,
We have an old invoice in Mews that was paid through another system. As part of our cleanup, we would like to register an external payment against this invoice.
However, when we try to do so, we receive the following error message: “Cannot specify both BillId and InvoiceIds.”
We initiate the process from the invoice by selecting Add External Payment, but the window that opens asks us to create a new bill. And although we choose to do so, we are unable to register the payment against the existing invoice.
Could you please explain why this is happening and how we can resolve it? Is there a recommended way to register an external payment for an existing invoice in this situation?
Thank you in advance for your help.
Kind regards,
Daira
