After a payee has submitted a registration, that registration has been approved and made its way into the ERP, and the vendor number (and possibly site code) from the ERP has been returned to PaymentWorks, the payee is considered to be “connected”. At that point, any subsequent changes the payee makes to the their vendor master information will be reflected in Updates, or in the case of remit and order addresses (not enabled for all customers), those will come in as edit registrations.
