  Check Existing Schema Aliases: Review the existing schema aliases in your project to see if the alias you are trying to use already exists. You can do this by navigating to the relevant section in the SAP Gateway Service Builder (transaction code /IWBEP/SEGW).
  Rename the Schema Alias: If the schema alias is already in use, consider renaming the new schema alias to something unique that does not conflict with existing ones.
  Delete Unused Aliases: If there are schema aliases that are no longer needed, you can delete them to free up the name for reuse.
  Consistency Check: Perform a consistency check on your project to ensure that there are no other issues that might be causing the error. This can often be done within the Service Builder.
  Consult Documentation: Refer to the SAP documentation or help resources for more detailed guidance on managing schema aliases and resolving conflicts.
