M1 arrival process enabled. CBP states that the net effect of this deployment is that the correlated arrival process in ACE M1 is now enabled and will perform arrivals on all manifests received, including manifests it receives from AMS.

Dual M1 and AMS processing. The dual processing between ACE M1 and AMS ensures that events generated from ACE M1 should be sent to AMS participants.

Fixes in works. CBP notes that the issues that have already been identified with this process are being fixed, and will be communicated to the trade when available.
