  The SAP error message VHU01051: Class &1 cannot be converted typically occurs in the context of vehicle management or classification processes, especially when dealing with vehicle classes in SAP Vehicle Management System (VMS) or related modules.
  
  Cause
  This error usually indicates that the system is trying to convert or map a vehicle class (or a classification object) that is not compatible or not allowed for conversion in the current process. Possible reasons include:
  
  The class &1 (where &1 is the class name or ID) is not defined for conversion in the system.
  The class is of a type that cannot be converted due to system restrictions or missing configuration.
  There is a mismatch between the expected class type and the actual class being processed.
  The class might be obsolete, deleted, or not maintained properly in the classification system.
  The conversion logic or program does not support the class type or the class is not assigned to the relevant object category.
  
  
  Solution
  To resolve the error, consider the following steps:
  
  
  Check Class Definition:
  
  Verify the class &1 in transaction CL02 (Change Class) or CL03 (Display Class).
  Ensure the class is active, correctly maintained, and assigned to the correct class type.
  
  
  
  Verify Classification Setup:
  
  Check if the class is assigned to the correct object type or vehicle category.
  Confirm that the class is allowed for conversion in the relevant customizing settings.
  
  
  
  Review Conversion Program or Process:
  
  Identify the program or process triggering the error.
  Check if the program supports the class type &1.
  If custom code is involved, debug or review the logic to handle the class conversion properly.
  
  
  
  Check for Notes or SAP Documentation:
