In the Serial number field you can choose a serial number from the product register, enter a serial number that does not exist in the product register or leave the field empty if no serial number is required. We recommend that you enter or select a serial number but this is not mandatory. A serial number can have a maximum of 40 characters.
If you select a serial number from the product register, the Delivery address and information in the section Service object will be loaded from the serial number.
If you choose a serial number on an already saved service order and the customer order on that serial number does not coincide with the customer order on the service order, a question appears asking if you want to replace the customer on the service order with the customer on the serial number. You can either say Yes or No to this question.
