If you want to resend 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 TopigsTatto. You can then register the TopigsTattoo number on the boar after, but in this case you have to resend the service.
Add the "Topigs tattoo"-column to the list "AI-boars".
You resend 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) og paste them in the datefield (press Ctrl+V).
Now the data will be sent to Topigs using "EDI pigs".
