A job that reprocesses incrementally-loaded files reads the files that were modified during the time that you specify. You can choose to reprocess files that were modified in a given time interval or all files modified after a given start time. Reprocessing applies only to Source transformations that you configure to incrementally-load files. The following image shows the reprocessing settings in

Advanced Options

:

You can reprocess source files when at least one source is configured to incrementally load files and the files have been loaded at least once. The advanced options are not available if the mapping does not have sources configured to incrementally load files, the mapping task has never run, or the mapping task is configured to perform a full load of all files.

Reprocessing doesn't change the time that the mapping task uses in future jobs to identify modified files for incrementally-loaded sources. For example, you have a mapping task that incrementally loads files and is scheduled to run every Monday at 8 a.m. After you run a job with advanced options on a Thursday, the next scheduled job still checks for files modified after Monday at 8 a.m. If you want to change the time that the mapping task uses to identify modified files, override the incremental file load type in the mapping task configuration.
