  Removing or replacing the inappropriate rules.
  Ensuring that only processing-related rules (like mapping or transformation rules) are applied to the structure fields.
  
  
  
  Consult Documentation: Refer to the SAP documentation or help resources for guidance on the types of rules that can be applied to structure fields.
  
  
  Testing: After making the necessary changes, test the data migration or transformation process again to ensure that the error is resolved.
