CRE does not have the same functionality as the "classic" version of Crystal - it doesn't connect to all of the same types of data, although CRE does connect to some things that Crystal does not (like .unx universes). I suspect that this is what you're running into. If that's the case, SAP won't classify it as a "bug" as such. Instead, it would be either "not yet implemented" or "by design".
