  Cause:
  This error message is usually triggered when you attempt to delete a node in a hierarchy that has reference nodes associated with it. In hierarchical data structures, nodes can have parent-child relationships, and deleting a parent node may lead to the deletion of its child nodes (reference nodes) as well. The system is informing you that the deletion of the node you are trying to perform will also affect other related nodes.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Hierarchical Structure: Review the hierarchy to understand the relationships between the nodes. Identify which nodes are considered reference nodes and how they are linked to the node you are trying to delete.
  
  
  Delete Reference Nodes First: If you intend to delete a node and its reference nodes, you may need to delete the reference nodes first before deleting the parent node. Ensure that you are aware of the implications of deleting these nodes.
  
  
  Use Transaction Codes: Depending on the context, you may be using specific transaction codes (like OMX1, OMX2, etc.) to manage organizational units or other hierarchical data. Make sure you are following the correct procedures for deletion.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on managing hierarchical data structures. This can provide insights into best practices and potential pitfalls.
  
  
  Check Authorizations: Ensure that you have the necessary authorizations to perform deletions in the system. Lack of proper permissions can sometimes lead to unexpected error messages.
  
  
  Backup Data: Before performing deletions, consider backing up the relevant data to prevent accidental loss of important information.
  
  
  Consult with SAP Support: If the issue persists or if you are unsure about the implications of deleting certain nodes, consider reaching out to SAP support or your internal SAP team for assistance.
