Configuring Receiver Message Tracking (NRR)
As part of the settings on this page, you can specify whether the inbound messages and their acknowledgements (MDNs) are stored in the non-repudiation database. For more information, see AS2 Processing in BizTalk Server.
To store messages in the non-repudiation database, the parties must enable NRR (Non-repudiation of receipt) as part of the AS2 agreement properties. NRR ensures that the sender party has verified the signed receipt from the message recipient. Conceptually, an NRR is an undeniable proof for the message sender that the message reached the destination unaltered. NRR can be established only when the original message and the receipt are digitally signed.
No properties are disabled on Party A->Party B one-way agreement tab if you cleared the Local BizTalk processes messages received by the party or supports sending messages from this party check box for Party A. However, all the properties are disabled on the same page in the Party B->Party A tab if you selected the check box while creating Party A.
You must be logged on as a member of the BizTalk Server Administrators or BizTalk Server B2B Operators group.
To configure message tracking for inbound AS2 messages and outbound MDN
Create an AS2 agreement as described in Configuring General Settings (AS2). To update an existing AS2 agreement, right-click the agreement in the Parties and Business Profiles page, and click Properties.
On a one-way agreement tab, under Local Host Settings section, click Receiver Message Tracking (NRR).
To guarantee non-repudiation of receipt, you must establish the authentication and integrity of the message. The recommended way of doing so is by using a digital signature on the message. As a result, if you select any of the properties to store messages in the non-repudiation database, you should sign the message by selecting the Message should be signed property on the Validation page.
Select NRR enabled for inbound encoded AS2 messages to store outbound encoded AS2 messages in the non-repudiation database.
Select NRR enabled for inbound decoded AS2 messages to store outbound decoded AS2 messages in the non-repudiation database.
Select NRR enabled for outbound MDN to store inbound MDN in the non-repudiation database.
