  Review Configuration: If you have the necessary permissions, check the configuration settings for the hierarchy in the relevant customizing transaction (e.g., OKEQ for cost centers). Ensure that the hierarchy is set up correctly to allow the desired insertions.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on managing hierarchies in your version of SAP.
