Makes it possible to take into account the previous account balances at the date of the extraction. It is the case if the period overlaps two financial years, for the reason of a gap in the finacial year end closure between companies. The principle is to calculate the accumulated balance at the end of the period preceding the extraction for the balance sheet accounts and to balance this in a suspense account. There is no recovery of the balance for management accounts.

It should be noted that if the Earlier balances box is checked, whether or not the extraction overlaps 2 fiscal years, from the moment that the extraction start date matches a fiscal year start date and a carry-forward entry exists, the carry-forward entry journal is taken into account in the extraction.
