  Causes of MR051 Error

  Invalid Characteristic Value: The value being entered may not be valid for the defined characteristic. This could be due to constraints set in the characteristic definition.
  
  
  Incorrect Formatting: The numeric value may be incorrectly formatted, such as using a comma instead of a period for decimal points, or including invalid characters.
  
  
  Missing or Incorrect Unit of Measure: If the characteristic is associated with a unit of measure, and that unit is not specified or is incorrect, it can lead to conversion errors.
  
  
  System Configuration Issues: There may be issues with the configuration of the characteristics in the classification system, such as incorrect settings in the characteristic definition.
