There is more than one record in the zip code table in the default geospatial tables that are deployed with the TIBCO Spotfire product. The duplicate records are driven by the fact that one zip code can be located in more than one city. If you could please add a primary flag to this table stating which record is the primary record, it would eliminate the duplicate error message in the visualization that duplicate zip codes were found. The function to suppress this error is not working.
