Using Extended by Relations in Assimilated Files

You can use the Extended by relation to add more data to an assimilated file without actually changing the file. The Extended by relation allows you to specify a one-to-one relationship between the existing file and a new, extended file that contains the additional fields you want to add. You will get automatic validation and existence checking and be able to define virtual fields from either file into the other.

Using Extended by relations also helps you save disk space because you can choose only to create records in the extended file when and if the data is needed.
