Update of Invoice reference and status in a sales order

Summary:

Hi,

I need to use a custom transaction source to differentiate Invoices that for the same country (Portugal) have different tax localization attributes.

Changing transaction source in AR Interface, from the standard one to the custom. The invoice get generated but order is not update with invoice reference and status remains in awaiting billing. Do you know if there is a way to update them in order to create referenced credit note?

Thanks,

Andrea
