You can use three interfaces to create Essbase applications: Administration Services Console, Essbase Studio, and the Application Library. Access Application Library through EPM Workspace.
Essbase applications created through Administration Services Console and Essbase Studio are known as Classic Essbase applications. Classic applications are stand-alone applications that do not share dimensions and members with other applications. Essbase applications created using the Application Library of Performance Management Architect are known as Performance Management Architect Essbase applications. These applications can share dimensions and members with each other.
Behavior of Essbase applications is identical regardless of the interface that is used to create them.
