This error indicates that a specific field in a business process must have unique values across its entire validity period, but the data being processed does not meet this requirement.
  Cause:
  The error arises when the system detects duplicate values in a field that is expected to be unique. This can happen due to:

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Duplicates: 
  
  Review the data in the source system to identify any duplicate entries for the specified field. You can use SQL queries or data analysis tools to find duplicates.

  Check Data Mapping:
  
  Verify the data mapping configuration in the migration tool. Ensure that the fields are correctly mapped and that there are no unintended overlaps.
  
  
  
  Adjust Business Rules:
  
  If the uniqueness requirement is too strict for your business scenario, consider adjusting the business rules or validity periods to allow for the necessary data structure.
  
  
  
  Test Migration:
