  Solution:
  
  Verify Parent Node: Check the current parent node of the data element you are trying to modify. Ensure that the new parent node you are trying to assign is indeed different from the current one.
  Select a Different Parent: If you intend to change the hierarchy, select a different parent node that is not the same as the current one.
  Review Hierarchical Structure: If you are unsure about the hierarchy, review the existing structure to understand the relationships between nodes before making changes.
  Consult Documentation: If you are working with a specific module or application within SAP, refer to the relevant documentation or help resources for guidance on managing hierarchical data.
