  Reassign or Change Hierarchy: If you need to remove the root node, consider reassigning its children to another node or restructuring the hierarchy.
  Use Appropriate Transactions: Ensure you are using the correct transaction codes or methods for managing hierarchical data. For example, use transaction codes like PFCG for roles or OM for organizational management.
