• What is the cause and solution for SAP error message FDT_EXPRESSIONS107 - Condition of node &1 does not have a boolean result ?

  The SAP error message FDT_EXPRESSIONS107 indicates that there is an issue with a condition in a decision node within a decision table or expression in the SAP system. Specifically, the error states that the condition of the node does not yield a boolean result (true or false). This typically occurs in the context of using the SAP Fiori Decision Table or similar functionalities where logical conditions are evaluated.
  Cause:
  
  
  Non-Boolean Expression: The condition defined in the node is not returning a boolean value. This could be due to:
  
  Using an expression that evaluates to a numeric or string value instead of a boolean.
  Incorrect syntax or logic in the condition that prevents it from being evaluated as true or false.
  
  
  
  Data Type Mismatch: The data types of the operands in the condition may not be compatible, leading to an inability to evaluate the condition correctly.
  
  
  Missing or Incorrect Operators: The logical operators used in the condition may be incorrect or missing, which can lead to an invalid expression.
  
  
  Solution:
  
  
  Review the Condition Logic: Check the condition defined in the node. Ensure that it is structured to return a boolean value. For example, conditions should typically be in the form of comparisons (e.g., A > B, C == D, etc.).
  
  
  Check Data Types: Ensure that the data types of the variables or fields being compared are compatible. If necessary, convert data types to ensure they can be compared logically.
  
  
  Correct Syntax: Verify that the syntax used in the condition is correct. Look for any typos or misplaced operators that could affect the evaluation.
  
  
  Use Logical Operators: Ensure that you are using the correct logical operators (AND, OR, NOT) to combine conditions if needed.
  
  
  Test the Condition: If possible, test the condition in a simpler context to see if it evaluates correctly. This can help isolate the issue.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on constructing valid conditions in decision tables or expressions.
  
  
  Related Information:
  
  SAP Fiori and Decision Tables: This error is often encountered in the context of SAP Fiori applications that utilize decision tables for business logic.
  Debugging Tools: Use debugging tools available in SAP to step through the logic and identify where the condition fails to evaluate correctly.
