CDS - Documents - The document has been sent but there's no Commission Reference and I cannot open (one of) the attachment file(s). Why?

Some Control Data documents are defined in SFC as possibly containing personal data. That's why they're encrypted in SFC2014. These documents do not have an ARES Commission reference. To be able to read (download) these documents from SFC you must have the MS Audit Personal Data Read (MSAPDR) role.
