  The SAP error message "09451 Selected unit of measure & is not a volume unit" typically occurs when a user attempts to perform an operation that requires a volume unit of measure, but the selected unit of measure (UoM) is not recognized as a valid volume unit by the system.
  Cause:
  
  Incorrect Unit of Measure: The unit of measure selected for the transaction is not defined as a volume unit in the SAP system. For example, using units like "pieces" (PC) or "kilograms" (KG) instead of "liters" (L) or "cubic meters" (M3).
  Configuration Issues: The unit of measure may not be properly configured in the system, or the mapping of units to their respective categories (like volume) may be incorrect.
  Master Data Issues: The material master data may not have the correct unit of measure settings for volume-related transactions.
  
  Solution:
  
  Check the Selected Unit of Measure: Ensure that the unit of measure you are trying to use is indeed a volume unit. Common volume units include liters (L), milliliters (mL), cubic meters (M3), etc.
  Change the Unit of Measure: If the selected unit is incorrect, change it to a valid volume unit that is recognized by SAP.

  Check UoM Configuration: If you have access to configuration settings, verify that the unit of measure is correctly defined in the system. This can be done in the following path:
  
  SPRO ? Logistics General ? Material Master ? Basic Settings ? Units of Measure ? Define Units of Measure.
  
  
  Consult Documentation: If you are unsure about which units are valid, refer to SAP documentation or consult with your SAP administrator for guidance.
