Reception Awareness

Application-level delivery reliability of the AS4 profile.

Definition

Reception Awareness gives the sending MSH the ability to notify its application when no eb:Receipt arrives. It relies on eb:Receipt as the sole acknowledgement, on optional retry (same MessageId, so the digest is unchanged to preserve non-repudiation) and on mandatory duplicate detection based on eb:MessageInfo/eb:MessageId.

Origin

Defined in section 3.2 of the OASIS AS4 Profile of ebMS 3.0 Version 1.0 (OASIS Standard, January 2013), through the PMode[1].ReceptionAwareness.* parameters.

Example in context

PMode[1].ReceptionAwareness=true; .Retry=true; .DuplicateDetection=true → the sender resends the same eb:MessageId until an eb:Receipt arrives, and the receiver eliminates duplicates.
