How are the periods in General Ledger synchronized to Cost Accounting?

The accounting periods defined in General Ledger are automatically copied to Cost Accounting when you click Open Target Period on the Manage Cost Accounting Periods page. It also synchronizes changes made to already copied periods that are in the Never Opened status.

If the newly defined periods or changes made to existing Never Opened periods aren't copied from General Ledger to Cost Accounting, then you can use an alternate method to synchronize the changes. For a cost organization and cost book combination, select Copy Periods from General Ledger from the Actions menu. This will copy the newly defined periods and the changed periods in General Ledger into Cost Accounting. Do note that the changed periods will be synchronized in Cost Accounting only if they're in the Never Opened status.
