Policies vary for each organization. Expense policies are set by your organization's Fyle admins to ensure that all details are captured in the expenses and they go through a certain process for approval.
If your company has an additional approval system in place for certain expenses as per policy. Additional approvers could include Secondary Approvers, Department Heads, and Project managers.
As per a certain policy, if an expense requires additional approval from the Department Head, and there is no Department Head configured, the policy will get triggered and the expense will not be submittable for approval (if the policy conditions do not allow the expense to be claimed).
You will be able to view the details of such policy failures from the expense History tab while you are verifying/viewing a particular expense within a report.
NOTE: All policy violation details (not limited to approvers) are visible in the History tab.
