  Use Temporary Variables: If you need to manipulate the value of the source object, consider using a temporary variable to hold the value before assigning it to the result object.
  
  
  Debugging: If you are unsure where the error is occurring, use debugging tools available in SAP to trace the execution and identify the exact location of the problematic assignment.
  
  
  Consult Documentation: Refer to SAP documentation or help resources related to the specific module or functionality you are working with. This can provide insights into proper usage and examples.
