If a destination herd is not specified in the app and you apply for a movement cert then you will get an error from Dept when applying saying "Move To Herd ID must be provided (E2632).
This is due to a new rule change from the 4th of February where all movement certs must have recorded the destination herd when applying for the cert.
Don't worry its easy to fix!
