  The SAP error message LTR2_ES_CHECK161 indicates that a filter (identified by &1) is assigned to a data model (identified by &2), but it is not being utilized in any of the data model's queries or processes. This situation can arise in SAP systems that utilize data models for reporting or data processing, such as SAP BW (Business Warehouse) or SAP HANA.
  Cause:

  Configuration Issues: The filter may have been created for a specific purpose, but the corresponding queries or reports were not updated to include it.
  Data Model Changes: Changes in the data model or the queries may have rendered the filter obsolete.
  
  Solution:
  
  Review Filter Usage: Check the queries or reports associated with the data model to see if the filter is indeed not being used. You can do this by examining the query definitions in the SAP BW or HANA modeling tools.
  Remove Unused Filters: If the filter is confirmed to be unused, consider removing it from the data model to clean up the configuration and avoid confusion in the future.
  Update Queries: If the filter is intended to be used, update the relevant queries or reports to include the filter. Ensure that the filter conditions are correctly applied in the query logic.
  Documentation: Document any changes made to the data model or queries for future reference and to maintain clarity in the data model's design.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for your specific version of SAP BW or HANA for detailed guidance on managing filters and data models.
  SAP Community: Engage with the SAP Community forums to seek advice from other users who may have encountered similar issues.
