I am trying to fetch UsedLicenses / TotalLicenses from UserLicense object and I am using API 32.0 but when I try to access those fields, error says "No such column 'UsedLicenses' on entity 'UserLicense'. If you are attempting to use a custom field, be sure to append the '__c' after the custom field name. Please reference your WSDL or the describe call for the appropriate names." Also by using developer console I am not able to do that. please suggest.
