Record/submit Data in Compliance with UNC

Customer Change Team Leader


Prior to the Project Nexus Implementation Date, Shippers were able to submit, and have accepted, Contact Detail updates with the same effective date as the date on which the transaction was submitted to UK Link systems even where they were not processed on the day of receipt by the CDSP.

Following Nexus implementation such transactions have been rejected. This CP seeks to develop a solution that reverts the outcomes of such Shipper transactions to those experienced prior to Nexus.
