What country is that, if you don't mind me asking? I wouldn't be surprised if it was Italy...
Anyway, ATPL exams are EASA and are valid everywhere in Europe. There's absolutely no difference between them. If you want your licence to be issued by a specific EASA country, you need to transfer your medical certificate to that specific country because your licence can be issued only by the country that holds your medical record.
You need the SOLI form to be released by the country that holds your current medical record.
