  Data Validation: If you are using a data upload or migration tool, validate the data being uploaded to ensure that there are no self-references in the product group assignments.
  
  
  Use Different Product Group: If you need to create a hierarchy or relationship, consider using a different product group as the parent or reference instead of the one you are currently working with.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on product group assignments and hierarchy configurations.
