Specifically, the error states that the default driver you are trying to assign is already assigned to another vehicle resource.

  Review Configuration:
  
  Check the configuration settings in the system to ensure that the assignment rules for drivers and vehicle resources are set up correctly.
  If necessary, consult with your SAP Basis or configuration team to adjust these settings.
