    error message "invalid expression" while loading

      Hello,

      When executing the following code:

       

      ElectricityDaily:

      LOAD Date,
      ShortDate,
      Type_ID,
      MonitoringPoint_ID,
      sum(Value_E) as Value_E_Daily,
      Unit_ID
      FROM [QVDs\Data.qvd] (qvd)
      GROUP BY ShortDate;




      I get the error "Invalid expression"

      I have no idea what the problem is...
