  Custom validation logic in user exits or BAdIs.
  Using SAP standard reports or transaction codes to identify duplicates.
  
  
  
  Adjust Configuration: If the error is due to configuration settings, consult with your SAP administrator or functional consultant to determine if the uniqueness requirement can be adjusted based on business needs.
  
  
  Data Cleansing: If the error arises from imported data, perform data cleansing to remove duplicates before importing into SAP.
