This error typically arises when you are trying to perform an operation that involves two different units of measure that cannot be converted or are not compatible with each other.

  Correct Data Entry: If the error is due to incorrect data entry, correct the entry to use the appropriate unit of measure.
  Consult Documentation: If you are unsure about the units of measure or how to configure them, consult the SAP documentation or reach out to your SAP support team for assistance.
