  Modify the Ruleset:
  
  If you find that a key column is already present, you can either remove it from the new addition or modify your ruleset to avoid duplication.

  Consult Documentation:
  
  Refer to the SAP documentation for the specific module you are working with to understand the ruleset configuration better and ensure compliance with the expected structure.
  
  
  
  Testing:
