Use posting periods to specify when users can post to the general ledger.
These posting periods apply to the company and to all users. To allow for exceptions, you can define different posting periods for specific users in the User Setup window. These posting periods overrule those specified in the General Ledger Setup window. For more information, see the "To set up user time constraints" section in How to: Manage Users and Permissions.
