Undoing a Year End Close
To undo a year end close, enter the ledger group, ledger (if necessary), fiscal year, and business units that you want to unclose.
When you run an undo for a year end close and you elect not to create journal entries, the system clears the period 999 (results of year end close) and period 0 (balance forward) rows from the ledger. To create journal entries, the system deletes the journal entries and clears the period 999 and period 0 rows.
