The Delivery Address (physical address to where the ordered goods should be delivered from Supplier) should be specified correctly in the Purchase Order.
Initially, the Company Address will be used automatically as default Delivery Address. The Delivery Address can be changed for this particular Purchase Order using predefined list of Delivery Addresses or can be changed manually (when the temporary values should be used). The Our Reference details (e.g. contact details of our Purchase Manager who is responsible for contacts with this particular Supplier) can be also changed.
