Hi.
There seems to be a limit on the amount of data that can be imported by this method:
http://communities.bentley.com/products/geospatial/desktop/w/geospatial_desktop__wiki/27355.how-to-create-a-vrt-file-in-bentley-map-to-import-csv-file
The Interoperability tool will not import more than 15,450 entries when using VRT file. Some of the overflow data can be seen in preview, but no parameters are imported.
Also, if there is any method that allows defining datatypes in the csv or vrt, this would be very interesting.
