  Review Input Items: Check the input items being used for the calculation. Ensure that at least one of the input items provides absolute values or is of a type that can contribute to the output calculation.
  Adjust Calculation Schema: If applicable, review the calculation schema or rules defined for the output item. Ensure that it is set up to accept the types of input items you are providing.
