In the print/send orders function, it can be easy to accidentally upload an order to a vendor multiple times. As a means to mitigate this error I propose a two part feature.

As a first step, the system should provide some indication when viewing the orders to ftp queue if an order has already been ftp'd once. I could see two methods for accomplishing this. 1) Add a column to the queue display for sent date, taking the most recent date present that has been appended to the ISBN pick field in a record from having been previously sent. 2) highlight any orders in red or blue where a sent message already exists in an ISBN pick field, similar to how duplicate invoices are colored in the import invoices function.

The second potential piece of this would be to generate a pop-up message along the lines of "File contains previously sent orders, do you wish to proceed?" that would appear at the point where the individual orders are packaged together into a single file for uploading to the vendor. That message would allow staff the opportunity to back out if they wish and remove any offending orders before proceeding.
