This update includes the following changes: Updated the definition for the F127 “Import Date Missing” validation to remove the language pertaining to the “Blanket Recon” logic where an Approved Reconciliation Importer that has been set up for ‘blanket’ NAFTA reconciliation must include the Date of Importation when making a NAFTA Reconciliation claim. The concept of "Blanket Recon Approval" was removed from the AE CATAIR with revision #49 and the validation has been updated accordingly. Removed Error F118 'RLF Requires Continuous Bond', as this was an older validation that was retired in January 2019.
