When you configure message recovery for a real-time session, the PowerCenter Integration Service can recover unprocessed IDoc messages from a failed session. When you enable message recovery for a real-time session, the PowerCenter Integration Service stores IDoc messages in a recovery file. If the session fails, run the session in recovery mode to recover the IDoc messages that the PowerCenter Integration Service did not process.
To enable message recovery, select Output is Deterministic in the SAP/ALE IDoc Interpreter transformation.
If you configure a transformation as repeatable and deterministic, it is your responsibility to ensure that the data is repeatable and deterministic. If you try to recover a session with transformations that do not produce the same data between the session and the recovery, the recovery process can result in corrupted data.
