'Linked Table' in the Report Data Definition

I am trying to add our 'Legacy' part number to all of the part numbers
in the Job Traveler. In the RDD for the Job Traveler, there are
several 'Linked' tables for each of the tables. Does anyone know if
you are able to create additional 'Linked' tables? I have added data
to the zlookuplink and zlookupfield tables that define the
relationships. I now see the 'LegacyPart' entry in the 'Linked' table
listing for JobAsm, JobMtl and SubASsmb in the RDD. However, when I
execute the Report using my new report style, the 'Linked' fields are
not appearing in the XML file. Each of the tables have the 'Linked'
fields in the XML file but the actual data is not present.
Any ideas? Do I need to create the new index in Progress like we did
in SQLServer?

Thanks,
