This error indicates that the system has encountered multiple instances of a header element that should be unique, leading to ambiguity in processing.
  Cause:

  Modify Queries/Reports: If you are working with a report or query, check the logic to ensure that it correctly handles cases where multiple records might exist. You may need to adjust the aggregation or filtering criteria.
  Use Distinct: If applicable, use a DISTINCT clause in your SQL queries to eliminate duplicate records from the result set.
