Payment Transaction ID for Invoice Payments

In the previous release, we added the ability to choose the payment reference that should be used for sales order and invoice payments. There are three options: customer number, order number, and PSP reference (payment transaction ID). They are all supported for sales orders, but PSP reference was not supported for invoices at that time. Now when customers pay their invoices in the Sana webshop, the PSP reference can be used for invoice payments and stored in the customer payment journal.
