If you cannot see the option to select the non-integral document 'MS form of designation (e.g. decree-law) of the MA/CA' is because the DoA has not yet been sent to the Commission.
This change was requested by DG REGIO and implemented in November 2017.
In this way the Member State can send the document associated to the process only when the Authorities have been notified to the EC and not before.
Thus this type of document can only be sent after the DoA object has been sent to the EC.
