Use this page to enable the period locking on a calendar. This is a convenient way to introduce a disabling reports policy for locked periods. Users will still be able to add or edit work logs, using the standard Jira interface or Jira REST API.
Please note that, as administrator, you can define the editors for period locking. Multiple groups and users can be set as editors. The period locking will not affect the editors, and they will be able to create and edit the events (worklogs and planning) for the locked periods.
