Mapping content
If the data contains columns of information that you do not want to import, do not map the columns to the database in the Import Wizard.
The property tables for each dimension are listed in the order in which they should be defined or mapped, because of dependencies between several of the dimensions.
If data for multiple dimensions are in one text file, the order of each dimension's data within the text file does not matter. It is the order in which dimensions are mapped that is relevant.
