• What is the cause and solution for SAP error message FDT_EXPRESSIONS369 - Switch for rule on position &1 has to be of a boolean value (Activity &2) ?

  The SAP error message FDT_EXPRESSIONS369 indicates that there is an issue with a rule in the context of the SAP Fiori Data Transformation (FDT) framework. Specifically, the error states that a switch for a rule at a specified position must be of a boolean value. This typically occurs when a condition or expression that is expected to evaluate to true or false is instead returning a different data type.
  Cause:
  
  Incorrect Data Type: The switch condition in the rule is not defined as a boolean value (true/false). This could happen if the expression is returning a string, number, or any other data type instead of a boolean.
  Misconfiguration: There may be a misconfiguration in the rule setup where the expected boolean expression is not correctly defined.
  Logical Errors: There could be logical errors in the expressions used in the rule that lead to an unexpected data type being returned.
  
  Solution:
  
  
  Check the Rule Definition: Review the rule definition at the specified position (&1) and ensure that the switch condition is correctly defined to return a boolean value. 
  
  Ensure that any expressions used in the switch condition are explicitly returning true or false.
  
  
  
  Modify Expressions: If the expression is complex, break it down to ensure that each part evaluates to a boolean. You may need to use comparison operators (e.g., =, <>, >, <) to ensure the expression evaluates to a boolean.
  
  
  Testing: After making changes, test the rule to ensure that it behaves as expected and that the error no longer occurs.
  
  
  Documentation and Examples: Refer to SAP documentation or examples related to the FDT framework to understand how boolean expressions should be structured.
  
  
  Consult with Colleagues or SAP Support: If you are unable to resolve the issue, consider consulting with colleagues who have experience with the FDT framework or reaching out to SAP support for assistance.
