Unable to Upload Documents to Orders

As long as the order has not been approved and sent you will not get the option.  If the received date has been entered, you will also not get the option.  To upload an order you will need to remove the received dates and then you should get the option or approve and send the order to physician first.  If you do not need to send it to the physician, you can "Print and update as sent" to get the option to upload.
