Here is a new problem.  When a customer places an order, we create a sales order.  Sometimes there are back orders.  We create an invoice when items are actually delivered and all is good - however, if there is a back order - when we go to invoice the back ordered items, the ship to date reverts to the original sales order date.  I need the ship to date to be the same as the invoice date - is there a way to fix this when invoicing from a previous day?
