Alternative for CEO Expense Approvals (Overriding Approver Limitation)

Hi Team,

We are facing a challenge regarding expense reimbursements for our CEO (top of the hierarchy). Since the CEO has no line manager, they must select an Overriding Approver.

However, Oracle Fusion's design prevents selecting a direct report from the List of Values (LOV) as an overriding approver. This poses a significant risk to the CEO’s reimbursement process. While we are aware that a custom BPM/Workflow rule could route these claims to a direct report, we prefer to avoid creating new approval rules to keep our maintenance overhead low.

Has anyone found an alternative configuration (outside of complex workflow rules) to allow a direct report to be selected, or an alternative way to handle top-level executive approvals where no natural supervisor exists?
