  The SAP error message MSG_UH264 indicates that there is an issue with the hierarchical structure of nodes in a certain context, typically related to the use of reference nodes in a hierarchy. The message format suggests that it is related to a specific line and involves nodes that are not correctly linked as expected.
  Cause:
  The error message Line &1: Node &2 is not a ref. node of node &3 generally occurs in scenarios where:
  
  You are trying to reference a node that is not a valid reference node for the specified parent node.
