• What is the cause and solution for SAP error message FDT_EXPRESSIONS702 - &1 does not return a boolean result value ?

  The SAP error message FDT_EXPRESSIONS702 indicates that an expression in a formula or condition is expected to return a boolean (true/false) result, but it does not. This error typically occurs in the context of SAP's Flexible Data Import (FDI) or similar functionalities where expressions are evaluated.
  Cause:
  
  Incorrect Expression: The expression you are using may not be formulated correctly to return a boolean value. For example, it might be returning a numeric value or a string instead of a true/false result.
  Data Type Mismatch: The data types involved in the expression may not be compatible with boolean logic. For instance, using a string comparison that does not resolve to true or false.
  Logical Errors: There may be logical errors in the expression that prevent it from evaluating correctly.
  
  Solution:
  
  
  Review the Expression: Check the expression that is causing the error. Ensure that it is designed to return a boolean value. For example, if you are using a comparison operator (like =, >, <), ensure that it is correctly applied.
  Example of a correct boolean expression:
  IF (field1 > field2) THEN TRUE ELSE FALSE
  
  
  Check Data Types: Ensure that the data types of the fields or variables used in the expression are appropriate for the operations being performed. If necessary, convert data types to ensure compatibility.
  
  
  Use Logical Operators: If you are combining multiple conditions, ensure that you are using logical operators (AND, OR, NOT) correctly to form a valid boolean expression.
  
  
  Debugging: If the expression is complex, break it down into simpler parts and test each part individually to identify where the issue lies.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the specific syntax and requirements for expressions in the context you are working with.
