OLAP creates some attributes automatically when creating a dimension. These attributes have a unique type, such as "Long Description."
All dimensions can be created with long and short description attributes. If your source tables include long and short descriptions, then you can map the attributes to the appropriate columns. However, if your source tables include only one set of descriptions, then you can create and map just one description attribute. If you map both the long and short description attributes to the same column, the data is loaded twice.
Time dimensions are created with time-span and end-date attributes. This information must be provided for all Time dimension members.
