Updates the aggregate exposure values of one country and resolution of the aggregate portfolio, so aggregate exposure data may be edited directly without an import job.

Values of submitted rows overwrite the stored values for those rows; rows omitted from the request are unchanged. If validation fails, nothing is persisted.

For workers' compensation aggregate portfolios (source is Work Comp), resolution is one of State, County, or Postal Code, lobs values are drawn from the workers' compensation classes, and countryCode must be US.

Use the Get aggregate exposures values operation to retrieve the full row and column scaffold for a country and resolution.
