The placeholders &1 and &2 represent the two units involved in the conversion.
  Cause:
  
  
  Missing Unit Conversion: The primary cause of this error is that there is no defined conversion factor between the two units specified in the error message. For example, if you are trying to convert between "liters" and "gallons" and there is no conversion defined in the system, this error will occur.
  
  
  Incorrect Unit Configuration: The units may not be properly configured in the system, or the relevant unit of measure (UoM) settings may be incomplete or incorrect.
  
  
  Data Entry Errors: Sometimes, the error can arise from incorrect data entry where the wrong units are being used in a transaction or planning activity.
  
  
  Solution:
  
  
  Define Unit Conversion:
  
  Go to the transaction code CUNI (Unit of Measure Conversion) in SAP.
  Check if a conversion exists between the two units mentioned in the error message.
  If it does not exist, create a new conversion entry by specifying the source unit, target unit, and the conversion factor.
  
  
  
  Check Unit Configuration:
  
  Ensure that both units are correctly defined in the system. You can check this in the configuration settings for units of measure.
  Use transaction code CUNI to review and maintain unit definitions.
  
  
  
  Review Data Entry:
  
  Verify the data being entered in the transaction or planning activity. Ensure that the correct units are being used and that they are compatible.
  
  
  
  Consult Documentation:
  
  If you are unsure about the units or conversions, refer to SAP documentation or consult with a functional consultant who specializes in the RPM module.
