The regulation says "the Member State shall submit". So, this means that the programme authorities involved need to coordinate who enters and who sends the dossier. It is a single transmission with a single model in the implementing act and it cannot be split in two!
For example the Certifying Authority (CA) can provide the forecast and the Managing Authority (MA) can provide the implementation data and then they have to decide who will send it to the Commission, keeping in mind that not all Tables have to be provided for each submission period (CA is not involved in the 31/10 submission).
