This error is a safeguard to prevent duplicate entries, which can lead to data integrity issues.
  Cause:
  
  Duplicate Entry: The most common cause is that the object you are trying to create (indicated by &1 in the error message) already exists in the database.

  Solution:
  
  Check for Existing Object: Before creating a new object, check if it already exists in the system. You can do this by searching for the object using the relevant transaction code or report.
  Use Different Identifier: If you need to create a new object, ensure that you are using a unique identifier that does not conflict with existing entries.
  Review Input Data: Double-check the data you are entering to ensure it is correct and complete. Look for any fields that may be causing the system to recognize the object as a duplicate.
  Data Cleanup: If you suspect that there are duplicates in the system due to data migration or other issues, consider running a cleanup process to remove or merge duplicates.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines related to the object type you are working with.
