At the end of the closing cycle when you have finished processing intercompany transactions, you can close the period to prevent additional modifications to the transactions. If the Match/Validate Before Post option is set to Yes for the period, all matched transactions or mismatched transactions with a reason code must be posted before a period can be closed. If Match/Validate Before Post is set to No or Restricted, the system does not check before closing the period.
When you close a period, it is locked for future transactions, however you can continue to view transactions or run reports on the period’s transactions.
