To meet the new requirements, our client decided to change their Year End near the end of the calendar year. This required the current calendar year to be a short year and then start on a new fiscal year basis end September 30. This decision was not made until November and this forced a back-end change to be accomplished. The major steps included unposting and posting all October and November journal entries, reconverting all 12 currencies, and re-consolidating all 45 Sets of Books. This process was done twice in Test prior to production. There were zero defects because of the extensive testing. The production conversion took less than a day.
