    Hi Brandon,

    There is no option on File event listener which would cause it to go "back". You have two options:

    • change the timestamp of those files you want to re-process. For example, using UNIX touch command. That would "draw" listener's attention and it would trigger the processing.
    • create a job flow which would pick your files and send them for processing to your standard file transformation graph - very much like the event listener is doing, but you would control which files get picked


    Example of simple jobflow picking files & sending them to be process by transformation graph (which would be the graph/jobflow called by your listener):


    The filter can have condition like this to ensure you only pick certain file types created/last modified withing time interval:

    $in.0.lastModified >= 2024-05-20 && $in.0.lastModified <= 2024-05-23 &&
    !$in.0.isDirectory && getFileExtension($"xlsx"

    Those "hardcoded" dates can be replace by parameters - thus this becoming unversal "re-run" for your files if processing by event listener fails.
