SummaryOverriding Approver should be in supervisory hierarchy
We have defined the Overriding approver as defined in How To Define Expense Report Approval Rules With Override Approver (Doc ID 2213225.1)
However the user is able to select anyone in the organization as overriding approver. I do not want this for obvious reasons. I would like the user only to be able to select someone within their supervisory hierarchy. (maybe they need to skip their direct manager because they are on vacation, so it should go to their manager's manager).
Any suggestion appreciated. Below my set up.
