• What is the cause and solution for SAP error message FDT_EXPRESSIONS160 - &1 is no valid AND/OR parameter; element type boolean is required ?

  The SAP error message FDT_EXPRESSIONS160 indicates that there is an issue with the logical expressions used in a formula or condition within the SAP system, specifically in the context of the Flexible Data Import (FDI) or Flexible Data Transfer (FDT) framework. The error message states that the parameter provided is not a valid AND/OR parameter, and it requires an element of type boolean.
  Cause:
  This error typically occurs due to one of the following reasons:
  
  Incorrect Expression Syntax: The logical expression may be incorrectly formulated, leading to the system not recognizing the parameters as valid boolean expressions.
  Data Type Mismatch: The parameters being used in the AND/OR conditions are not of the expected boolean type. For example, if a numeric or string value is being used instead of a boolean value (true/false).
  Missing or Incorrectly Defined Variables: If the variables or fields used in the expression are not defined correctly or are missing, the system cannot evaluate the expression properly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Expression Syntax:
  
  Review the logical expression for any syntax errors. Ensure that the AND/OR operators are used correctly and that the expressions on either side of these operators are valid boolean expressions.
  
  
  
  Verify Data Types:
  
  Ensure that all parameters used in the AND/OR conditions are of the boolean type. If you are using fields or variables, check their definitions to confirm they are boolean.
  
  
  
  Debugging:
  
  If possible, use debugging tools to trace the execution of the expression and identify where the error occurs. This can help pinpoint the exact parameter causing the issue.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the FDT framework to understand the expected syntax and data types for logical expressions.
  
  
  
  Test with Simplified Expressions:
  
  If the expression is complex, try simplifying it to isolate the problem. Start with basic boolean expressions and gradually add complexity until the error reappears.
  
  
  
  Seek Help from SAP Community:
  
  If you are unable to resolve the issue, consider reaching out to the SAP community forums or support for assistance. Provide details about the expression and context in which the error occurs.
