• What is the cause and solution for SAP error message FDT_EXPRESSIONS397 - Node &1 is not an error node (actual node type: &2) ?

  The SAP error message FDT_EXPRESSIONS397 indicates that there is an issue with the node type in a decision table or expression in the SAP Fiori Decision Table framework. Specifically, the error states that the node you are trying to reference (Node &1) is not recognized as an error node, and it provides the actual node type (Node type: &2).
  Cause:
  This error typically occurs when:
  
  The node you are trying to access or manipulate is not defined as an error node in the decision table or expression.
  There may be a mismatch in the expected node type and the actual node type being processed.
  The configuration of the decision table or expression may be incorrect, leading to an invalid reference.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Node Configuration:
  
  Verify the configuration of the decision table or expression where the error is occurring. Ensure that the node you are referencing is correctly defined as an error node if that is the intended use.
  
  
  
  Review Node Types:
  
  Check the actual node type being referenced in the error message. Ensure that you are using the correct node type for your logic. If you are expecting an error node, make sure that the node is set up correctly in the decision table.
  
  
  
  Update Logic:
  
  If the logic in your decision table or expression is incorrect, update it to ensure that it references the correct nodes. This may involve changing the node type or adjusting the conditions that lead to the error node.
  
  
  
  Test Changes:
  
  After making the necessary changes, test the decision table or expression to ensure that the error no longer occurs and that the logic behaves as expected.
  
  
  
  Consult Documentation:
  
  If you are unsure about the configuration or the expected node types, refer to the SAP documentation for the Fiori Decision Table framework for guidance on how to properly set up nodes and expressions.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists after checking the configuration and logic, consider reaching out to SAP support for further assistance. They may provide insights specific to your implementation or version of SAP.
