• What is the cause and solution for SAP error message FDT_EXPRESSIONS322 - Message parameters do not match parameter positions ?

  The SAP error message FDT_EXPRESSIONS322 indicates that there is a mismatch between the parameters defined in an expression and the actual parameters being passed to it. This typically occurs in the context of SAP's Flexible Data Import (FDI) or similar data processing scenarios where expressions are used to manipulate or validate data.
  Cause:
  
  Parameter Mismatch: The number of parameters defined in the expression does not match the number of parameters being passed when the expression is called.

  Expression Definition Errors: There may be an error in how the expression itself is defined, such as missing parameters or incorrect syntax.
  
  Solution:
  
  Check Expression Definition: Review the expression definition to ensure that the number of parameters and their types are correctly defined.
  Verify Parameter Passing: Ensure that when calling the expression, the correct number of parameters is being passed and that they are in the correct order.
  Data Type Validation: Confirm that the data types of the parameters being passed match the expected data types in the expression.
  Debugging: If possible, use debugging tools to trace the execution and see where the mismatch occurs. This can help identify the exact point of failure.
  Documentation Review: Consult the SAP documentation or help resources for guidance on how to properly define and use expressions in your specific context.
