Customer Change Team Leader


Each month, by M-5, the .NRL file (AQ notification file) is issued from the CDSP to Shippers to notify of the new AQ/SOQ values (both rolling and Formula year that will be going live on the 1st of the month.

If there is a transfer of ownership in progress whose status changes to CO in the period following file generation and new AQ go live the incoming User is not notified of the new AQ/SOQ value.

The NRL file will only be issued to the live shipper at the point of file generation. The incoming Shipper will receive a TRF file, though that would contain the AQ which is effective at the point of time, and hence they will not learn of the planned revision to AQ and not have this information available to their systems.

This is Change was raised to provide the new User with a view of the amended AQ/SOQ

(there is already an approved change to provide a report for this scenario for Formula year values).
