  Simplify the Expression: If you are using an expression that includes identifiers, try to simplify it. Replace the expression with a literal value or a constant that does not involve identifiers.
  
  
  Use Alternative Approaches: If you need to use dynamic values based on identifiers, consider using other methods to achieve your goal. For example, you might need to use a different approach to construct your SQL or DDL statement programmatically.
  
  
  Check Documentation: Refer to the SAP documentation for the specific DDL statement you are working with to understand the allowed syntax and constraints for the & clause.
