  The SAP error message ITOB_FLEET401: "Enter the SI unit first" typically occurs in the context of the SAP Fleet Management module, particularly when dealing with measurements or quantities that require a standard unit of measure (SI unit) to be specified before other units can be entered.

  Check Input Fields: Ensure that you have entered the required SI unit in the designated field. This could be a field for length (meters), mass (kilograms), volume (liters), etc.
  
  
  Review Configuration: If you are consistently encountering this error, it may be worth reviewing the configuration settings in the SAP system to ensure that the units of measure are correctly defined and that the system is set up to recognize the SI units.
