Private dimensions
Private dimensions exist only in the current model and don't appear in the public dimensions list. When you create dimensions while importing data from a file or from SAP Business Warehouse, SAP ERP, SAP Universe, or other databases, they are created as private dimensions. When you delete a model, private dimensions in that model are also deleted, but the public dimensions are not. All dimensions have, at minimum, both description and ID attributes. Typically, for each dimension, the imported data column is used as the dimension's description attribute. An ID column is then automatically generated for each dimension to contain the unique IDs of the rows:
