This typically occurs in scenarios involving master data management, such as when dealing with organizational structures, product hierarchies, or other parent-child relationships in SAP.
  Cause:

  Data Validation: Ensure that the data being processed is valid and conforms to the expected structure. This may involve cleaning up the data or correcting any inconsistencies.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on the entities you are working with. This can provide insights into the allowed relationships and any constraints that may apply.
