An outbound transaction (message) in a stable end state can be manually replayed (by clicking Replay on the Advanced Search page after you select a completed transaction) one or more times. This function triggers the message exchange flow again to reprocess the transaction (message) in its entirety from the start, including exchange lookups, protocol-specific document packaging, and delivery to trading partner destinations. You can also replay multiple transactions at the same time.
Replay eligibility depends on the protocol and exchange profile pattern used. The replay status of a message is calculated based on whether a transaction is a replay of another transaction or if the transaction was replayed one or more times. Only processes that are in a stable final state (completed successfully, completed with errors, or failed) are available to be replayed.
You can easily replay (reprocess) failed exchanges, and you can replay a completed process multiple times. However, if a previous replay request is not complete, you cannot request another replay for the same transaction or process. If a replay is requested and the process that was restarted is not complete, you cannot request another replay of that process until the original replay request is completed.
The replay status of each Transaction ID is displayed on the Advanced Search page. You can use the replay status icons to track and correlate resent and original messages to view the entire history of the transaction, including the history of the associated reprocess. You can also easily search for replayable transactions, transactions that are a replay of a prior transaction, and transactions that have a replay.
You can see all the correlations between associated exchanges by using Advanced Search. For example, if a particular exchange is a replay of another exchange, it can also be replayed and redelivered one or more times. Each exchange that was replayed or redelivered one or more times and all of the correlated exchanges are delineated on the View Exchanges page.
