What's the difference between incomplete and unposted batch statuses?

All batches that aren't in a Posted status are considered unposted batches. These unposted batches have various statuses, including Incomplete, Selected for Posting, Processing, or Error.

A journal batch that is in an incomplete status has been saved, but is not completed. Incomplete journals are listed on the Incomplete tab of the Journals work area landing page and General Accounting dashboard.
