This typically occurs in the context of data migration or data transfer processes, such as when using the SAP Data Migration tools or during system upgrades.
  Cause:
  The error message is triggered when the number of records that could not be processed (lost records) exceeds the limit set in the system. This can happen due to various reasons, including:

  Correcting data types
  
  
  Adjust Thresholds: If appropriate, consider increasing the threshold for lost records in the migration settings. However, this should be done with caution and only if you are confident that the data quality can be improved.
  Test Migration: Perform a test migration with a smaller subset of data to identify potential issues before attempting a full migration.
  Consult Documentation: Refer to SAP documentation for specific guidelines related to the migration tool you are using, as there may be additional configuration options or best practices.
