I have a site that uses the Purchase Order payment method, how do I add the Purchase Order Number to the message template OrderPlaced.StoreOwnerNotification?
I am using V4 and noticed that Purchase Order Payment method is not available in this version? The PO Number used to be a field in the Orders Table in older versions and so it was automatically displayed on the page as part of the order details if it had been used.
So in previous versons it was easy to do some development an add a new token to display it in the message template.
