Not sure about your exact scenario but it appears you are using a custom polygon provider using your own boundaries? Note, that SAS VA ships with country-level boundaries for all countries. Just make sure you map data correctly given the expected IDs listed on http://support.sas.com/rnd/datavisualization/vageo/85/va85lookupvalues.html .
If you need to use custom boundaries - you need to make sure not exceeding the default vertices threshold of 250k vertices. This means regions aren't allowed to have more than that per geo map rendering request. If you have more than that - use tools like PROC GREDUCE or even better, use the provided %SHPIMPORT macro which does reduction automatically.
If you run into any other issue using custom polygons - the post

Hope this helps!
