We have added a feature to Advanced Approvals.
You can now add a time frame (in days) to bypass an approver.
For example, my AP Temp is added as the default approver on the below policy.
I have also added Accountant All locations. Under Escalation, I entered 12 (days).
This is saying that after 12 days, this policy will be escalated to Accountant.
This will not prevent AP Temp from approving, it is simply alerting another approver and allowing the invoice flow to continue.
