When 'Close General Ledger Periods' will complete with Warning?

Summary:

What are scenarios when 'Close General Ledger Periods' will complete with Warning?

Content (required):

After we closed GL ('Close General Ledger Periods' completed successfully), we have identified one accrual which did not reverse in closing GL period (journal has been posted after GL period was opened). We are wondering if this check is performed by the system when closing GL. We have this check as a manual step but it has been missed and now we are wondering how this can be avoided in the future.
