  Review Object Instances: If you are working with instances of objects, ensure that you are not inadvertently referencing the same instance. 
  
  
  Debugging: If you are unsure where the error is occurring, you may need to debug the process or workflow to identify the specific point where the link is being created.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more information on how to properly define links between business objects.
