We have orders importing from our eCommerce platform through ROI's Insynch.  Most of these orders have individual addresses that the customer types in, so we do not have these address saved in Sage or on their web stores.  In turn we do not have "shiptocodes" on most of the orders.  When we go to batch invoice orders the sales tax defaults to the "sold to" address and is greyed out in the SO Invoice data entry screen.  I read about someone trying to script an override ten years ago, I hoping there is an easy way by now.  I don't know how we would assign "shiptocodes" to all the addresses that are being imported.
