If you want to re-send data to Topis Norsvin using "EDI Pigs" you have to re-enter the date of the data.
An example could be if you, by mistake, have registered a service with a boar without Topigs Tattoo. You can then register the Topigs Tattoo number on the boar after, but in this case you have to re-send the service.
Add the "Topigs tattoo"-column to the list "AI-boars".
You re-send the service by searching for the AI-boar in the window "Service" and the re-entering the date. If it is several services you can mark the dates, copy these (press Ctrl+C on your keyboard) and paste them in the date field (press Ctrl+V).
Now the data will be sent to Topigs using "EDI pigs".
