  The SAP error message FDT_EXPRESSIONS332 indicates that there is an issue with a boolean expression in your SAP application, specifically that an invalid operand has been used where a boolean data object is required. This error typically arises in the context of using the SAP Fiori Design Time (FDT) or when working with expressions in SAP applications.
  Cause:
  The error occurs when:
  
  An expression is expecting a boolean value (true/false) but receives a different data type (e.g., string, integer).
  There is a syntax error in the expression that leads to an invalid operand being evaluated.
  The logic in the expression is incorrectly formulated, leading to a mismatch in expected data types.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the Expression: Review the expression that is causing the error. Ensure that all operands used in the expression are of the correct type. If the expression is supposed to evaluate to a boolean, make sure that all components of the expression return boolean values.
  
  
  Data Type Validation: Ensure that the variables or fields being used in the expression are indeed boolean. If they are not, you may need to convert them to boolean or adjust the logic to ensure that the expression evaluates correctly.
  
  
  Syntax Review: Look for any syntax errors in the expression. Ensure that all operators and functions are used correctly and that parentheses are properly placed.
  
  
  Debugging: If possible, use debugging tools to step through the code and identify where the expression is failing. This can help pinpoint the exact location and cause of the error.
  
  
  Documentation and Examples: Refer to SAP documentation or examples related to the specific context in which you are working. This can provide insights into how boolean expressions should be structured.
