• What is the cause and solution for SAP error message /STMC/CR_MSG609 - Selected node is not a leaf node ?

  The SAP error message /STMC/CR_MSG609 Selected node is not a leaf node typically occurs in the context of SAP's classification system, particularly when working with the classification hierarchy or when trying to perform operations on nodes in a classification tree.
  Cause:
  This error indicates that the node you are trying to select or perform an operation on is not a "leaf node." In a classification hierarchy, a leaf node is a node that does not have any child nodes. If you attempt to perform an action that is only valid for leaf nodes (such as assigning characteristics or values), and the selected node has child nodes, you will encounter this error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Node Type: Verify that the node you are trying to work with is indeed a leaf node. You can do this by checking the hierarchy structure to see if the node has any child nodes.
  
  
  Select a Leaf Node: If you need to perform an operation that requires a leaf node, navigate to a leaf node in the hierarchy and select that instead.
  
  
  Modify the Hierarchy: If you need to perform operations on the selected node, consider restructuring the hierarchy if appropriate. This may involve removing child nodes or changing the classification structure.
  
  
  Review Documentation: Consult the SAP documentation or help resources related to the classification system to understand the requirements for the operations you are trying to perform.
  
  
  Consult with SAP Support: If you are unsure about the hierarchy structure or how to proceed, consider reaching out to your SAP support team or consulting with SAP experts.
  
  
  Related Information:
