The Statistical Data Collection (SDCX) requires a country for calculating the base population. The country could not be determined for your Statistical Data Collection.
Solution
Ensure the GeoEnrichment Service contains the required country.
More information
The GeoEnrichment service uses standard geographic units to aggregate data for rings and other polygons—known as data apportionment. The standard geography is based on specific countries. If the country is not available, apportionment cannot be calculated for the Statistical Data Collection.
