Hi Andrea,
Sorry but I'm afraid depreciation run couldn't be reset or reversed. It has to be excuted one period after another. In some special cases, you can use 'unplanned depreciation' mode for depreciation posting, which will allow you to skip some periods, but the cumulated depreciation amount in the skiped periods will be added to the next depreciation run period. Besides, better test first before using unplanned depreciation mode for it may cause problem if not correctly used.
Best regards, Hannah
