  Check Object Model Configuration: Review the configuration of your object model to ensure that there are no other naming conflicts. This may involve checking the definitions of fields and aliases to ensure they are distinct.
  Review Documentation: Consult the SAP documentation for guidelines on naming conventions and best practices for creating aliases and fields within the object model.
