Vendor card has existing page for Order Addresses. This page has General and Communication sections. Communication includes phone, fax and email.

When used in a Purchase Quote/Order, selecting the Alternative Vendor Address code updates the buy-from address fields but uses the phone and email details from the main card. Vendors with alternative addresses will usually have different phone and email accounts for these locations.

The communication details should pull through from the order address into the Purchase header to match the order address details.

I appreciate a Contact record could be used instead, but it seems pointless having an order address that has communication details ignored in the document being sent out to it.
