Auto-Approve Time
If you do not want to approve time entries manually, you can use the Auto approve option. This is a Company level setting. If checked, time entries are automatically approved and the project financials updated as soon as they are submitted for approval. Managers will not receive email notifications to approve time. You can reject time even if it is approved automatically.
To enable automatic approval:
-  Login with a user with administrator privileges and click on Administration option under the user profile.
- Under the Timesheets section, click on Timesheet Options.
- Select the option Auto Approve under respective drop-downs under Approval Workflow section and click on Save.
Any time-entries submitted after this change will automatically be approved directly.
