В последних версиях BI 12.2.1.3(4)

По поду второго нашел

As documented at Oracle Essbase Readme (Release 12.2.1.2.0), this feature is not supported in the 12.2.1.2.0 release. So, any references to CDS, Essbase BI Acceleration, and Essbase BI Acceleration Wizard in the Essbase documentation should be ignored.
