You can map multiple columns to a composite domain or you can map a single column with delimited values to a composite domain. When you have multiple columns, you must map a column to each single domain in the composite domain to apply the composite domain rules to data cleansing. When you have a single column with delimited values, you must map the single column to the composite domain. The values must appear in the same order as the single domains appear in the composite domain. And, the delimiter in the data source must match the delimiter that is used to parse the composite domain values. For step by step instructions, see Map Columns to Composite Domains in Books Online.Carla Sabotta
