  Identify Duplicates: Check the database or relevant tables to identify where the duplicate sequence numbers are being generated. You can use transaction codes like SE16 or SE11 to view the relevant tables.
  Correct Data: Once duplicates are identified, correct the data by ensuring that each customer has a unique sequence number. This may involve updating existing records or creating new unique sequence numbers.
  Review Configuration: Check the configuration settings in the DSD module to ensure that sequence number generation is set up correctly. This may involve reviewing the settings in transaction codes like SPRO.
  Data Validation: Implement validation checks during data entry to prevent the assignment of duplicate sequence numbers in the future.
  Consult Documentation: Review SAP documentation or notes related to the DSD module for any specific guidelines or updates that may address this issue.
