Hello Experts,

We are currently using Oracle Fusion Expenses and would like to enforce a business rule regarding cash advances.

Our requirement is to prevent employees from requesting multiple cash advances simultaneously. Ideally, an employee should only be allowed to request a new cash advance after the previous cash advance has been fully applied to an expense report and is no longer outstanding.
