CORE allows you to automatically approve time and expense entries, if required. In such cases, employees do not need to submit their entries for approval. Under Settings > Time & Expenses > Time Entry, there are rules that allow you to auto approve time entries for projects and employees. If you have Auto approve time entries for projects checked, CORE ensures that time entries get automatically approved for all new projects. For existing projects, you have to enable the rule Auto approve time entries in the Projects > General > Assignment screen. Check CORE Help Center for details.
If Auto approve time entries for employees is checked, time entries logged by all new employees are automatically approved. If you want this to apply to existing employees, you need to check the Auto approve time option in the Employees > General > Rates & Options screen.
Note: The Auto Approve options set from Settings aren't applicable to existing projects or employees; they are applied to newly created projects or employees. Similarly, if you disable the auto-approve rules, it does not affect the existing entries, but only to the new entries. Check CORE Help Center for details.
