    That's related to Aurelius. Decimal is a record to "simulate" a primitive type, an Aurelius doesn't understand that - it's not supported. You would have to use native Delphi types in your mapped fields (like double or extended). You can still have your public property using Decimal type, but then you would have to use getters and setters to convert the Decimal public value to/from the private field
