Beginning in TTM6.1, DMSTAX and DMSCLE will be received as separate notifications for all declaration types and payment methods. This change is required to support CDS immediate payments, which is planned for a future Trade Test release, as per the Trade Test scope roadmap.
This was inadvertently deployed early into the Trade Test environment this morning but has now been reverted so that DMSTAX and DMSCLE are received as a consolidated notification as expected.
In terms of the technical context behind this change, the business rules codebase is currently configured to delay sending the DMSTAX notification for 1 hour, or to send it along with the next notification – DMSCLE in most cases – in a single consolidated message, whichever is sooner. This is why DMSTAX and DMSCLE have been received as a single notification for all declaration using deferred payment in Trade Test to date.
In TTM6.1 (implementation to begin out of hours on Monday, 25/02), this one hour wait will be removed to ensure DMSTAX is sent as soon as it is generated in immediate payments scenarios. However, this change will apply for all declaration types and payment methods, meaning that DMSTAX and DMSCLE will now be sent as separate notifications in all scenarios, though they will be received in quick succession for declarations using duty deferment.
CDS was already planning to make changes to the timing of the DMSTAX notification (to send it before the 10 minute dwell time starts) in response to your feedback on the current configuration of the dwell timer, which would have a similar impact. Splitting the notifications to facilitate immediate payments represents an earlier implementation of this change than you may have expected.
