Creation of modeling books no longer supported

As previously announced in a deprecation notice, the ability to create modeling books is no longer available in Planning Analytics Workspace as of 2.0.73. Existing modeling books continue to be usable, but all modeling activities are now supported in the Modeling Workbench.

You can review the deprecation notice here.
