  The SAP error message FDT_EXPRESSIONS335 indicates that there is an issue with an operand in an expression within the context of SAP's Flexible Data Import (FDI) or similar data processing scenarios. The message states that the operand specified (denoted as &1) at a certain position (denoted as &2) is neither recognized as a valid data object nor as a valid expression.
  Cause:
  
  Invalid Operand: The operand you are trying to use in your expression is not defined or recognized in the context where it is being used. This could be due to a typo, a missing variable, or an incorrect reference.
  Contextual Issues: The operand may not be valid in the specific context of the expression. For example, it might be trying to reference a field or variable that is not available in the current scope.
  Data Type Mismatch: The operand may not match the expected data type for the operation being performed, leading to it being unrecognized.
  Expression Syntax Error: There could be a syntax error in the expression itself, causing the operand to be misinterpreted.

  Check Operand Definition: Verify that the operand &1 is correctly defined and available in the context where it is being used. Ensure that it is spelled correctly and that it exists in the data model.
  Review Expression Syntax: Look over the entire expression for any syntax errors. Ensure that all operands are correctly formatted and that the expression adheres to the expected syntax rules.
  Validate Data Types: Ensure that the operand is of the correct data type for the operation being performed. If necessary, convert the data type to match the expected type.
  Debugging: If possible, use debugging tools or logs to trace the execution and see where the expression is failing. This can provide insights into what might be going wrong.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the specific context in which you are working. This can provide additional insights into valid operands and expressions.
