If there is no fix: I am the FE admin. My workaround was to create a second ID with my personal e-mail. Any credit card or invoices I submit I do so with my second ID. Works well.

This is a similar problem for our organization. Supervisors should have the ability to remove "Self-Approval" rights for everybody, including themselves. As I expressed to Blackbaud in a case, this design choice most likely goes against the internal controls of every single organization who uses it. Every expense needs some form of approval, Supervisor or not. We are trying to implement this system as a paperless alternative and we need to make sure every facet of Expense Management is compatible with our needs, with the most important aspect being internal controls.
