Select a dimension column from the list.
Select a Fixed Attribute, or select one of the two types of changing attributes. Use Fixed Attribute when the value in a column should not change; Integration Services then treats changes as errors. Use Changing Attribute to overwrite existing values with changed values. Use Historical Attribute to save changed values in new records, while marking previous records as outdated.
Select a dimension column, and remove it from the list of mapped columns by clicking Remove.
