    No.   journaling captures what has happened to the file in the receiver, it does not put records into the file.    The journal should be able to help you identify how/when the duplicates were put into the file.

    Journaling by itself would have no effect on creation nor existence of duplicate records. Journaling doesn't create records at all. However, by reviewing journal entries, you can find where duplicates are coming from. Duplicates are allowed in the file if the UNIQUE attribute isn't set. -- Tom

    Journaling just provides an audit trail of actions on the file. It does no adding of data. If duplicates are an issue them ypu need to make the file key "unique"
