  Review Tag Lengths: Check the configuration of the tags in the BRF to ensure that their maximum lengths are appropriate for the data being processed. If necessary, increase the maximum length of the tags to accommodate the data.
  Data Validation: Implement validation checks to ensure that the data being input into the system does not exceed the defined lengths. This can help prevent the error from occurring in the first place.
  Adjust Data Model: If the data model is not aligned with the actual data being processed, consider adjusting the data model to better fit the requirements.
  Testing: After making changes, thoroughly test the BRF rules and the associated data inputs to ensure that the error does not recur and that comparisons are functioning correctly.
