  Delete Child Nodes First: If you need to remove the first node, you must first delete all child nodes associated with it. This may involve:
  
  Deleting or reassigning any child nodes that are linked to the root node.
  Ensuring that there are no dependencies or references to the root node.
  
  
  
  Change the Hierarchy: If your goal is to restructure the hierarchy, consider:
  
  Changing the root node to another existing node if applicable.
  Creating a new hierarchy if the current one is no longer needed.
  
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific instructions on managing hierarchies in your version of SAP CRM.
  
  
  Seek Help from SAP Support: If you are unsure about the steps or if the hierarchy is complex, consider reaching out to your SAP support team or consulting with an SAP expert.
