This allows you to select a contact and the ship-to address associated with the contact. When you select a customer in the Sales/Invoicing window, the contact set up as the default ship to contact will appear in the Ship To fields by default; you can choose another contact and address using the drop-down arrow button next to the field.
You can edit a ship-to address for the sales invoice you are currently entering. After you select the contact you want to edit, simply click in the fields that you want to change and type in new data.
Note: This will not change the existing address information in the customer record.
