  This error arises when you attempt to perform an operation that requires a node to be a child of another node, but the selected node is already at the top level of the hierarchy.

  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Hierarchy Structure: Review the current hierarchy structure to confirm the position of the node you are trying to modify. Ensure that you are not trying to assign a top node as a child to another node.
  
  
  Select the Correct Node: If you intended to work with a different node, ensure that you have selected the correct one. You may need to navigate through the hierarchy to find the appropriate child node.
  
  
  Modify the Hierarchy: If you need to change the hierarchy, you may need to create a new node or adjust the existing structure to accommodate your requirements. This might involve creating a new parent node or restructuring the hierarchy.
  
  
  Consult Documentation: Refer to SAP documentation or help resources specific to the module you are working with (e.g., SAP Controlling, SAP Financials) for detailed guidance on managing master data hierarchies.
  
  
  Seek Help from SAP Support: If the issue persists and you are unable to resolve it, consider reaching out to your SAP support team or consulting SAP Notes for any known issues or patches related to this error.
