Select Dimensions (Cube Wizard)
In this step of the wizard, you choose dimensions for the cube. You can choose from previously defined dimensions, which are shared (that is, available to other cubes), or start the Dimension Wizard to create a new dimension. If you create a new dimension, you can define it as either shared or private (available only to the cube you are creating).
