When you validate or publish a schema, a warning displays if you do not have a Time dimension type. Although most cubes have a Time dimension type, it is not required and you can still publish the schema.

Additionally, a warning displays if the cube has more than one Time dimension type. For best results with multiple Time dimension types, create a separate hierarchy for each, with levels consisting of Time types.

For more information on foreign keys in fact tables, see Modeling Dimensions and Hierarchies.

  1. From the Schema Tree View, right-click the Dimension folder, and select New Dimension. An empty Dimension icon displays within the folder, and the Dimension page appears in the Schema Elements Properties view.
  2. In the Name box, type a name for the new dimension.
  3. Click the Caption box. The Caption box automatically fills the same name as the dimension. The caption is a name that is displayed and can be localized to different languages in the BI client application. See Cube Schema Localization.
  4. Select a dimension type from the Dimension Type menu. For more about dimension types, search “available dimension types” in the MS Developer Network Library at http://msdn.microsoft.com/library/.
  5. From the Leaf Members table, select the table associated with the dimension.
  6. Take time now to add dimension hierarchies. See Creating a Hierarchy for a Dimension.

    This populates the Default Hierarchy menu in the dimension Schema Elements Properties.

  7. Select the new dimension in Schema Tree View, and select an option from the Default Hierarchy menu.
