Manage Shipper Transfers

Customer Change Team Leader


This change has been raised in to deliver the requirements set out under UNC Modification 0811S, in order to provide a remedy for SARs that have failed to be progressed (exceptions) within a reasonable period, to be proactively managed by the Central Data Services Provider (CDSP).

Both Shippers should attempt to amend the transfer read in line with the SAR within 2 months after it was agreed. Currently only the Proposing User can submit the SAR to the CDSP. If this has not occurred, then under this change, the CDSP can be contacted for support and ensure the new agreed read is recorded centrally.

When the CDSP needs to be contacted for support, the Shipper should provide them with suitable evidence of the new agreed read.
The CDSP will then notify the other Shipper of the new agreed read and will, in the absence of any relevant rejection, process the new agreed read centrally.
