Is this a purpose of an IdentitylQ certification?

Certifying user expense reports isnota purpose of IdentityIQ certification. IdentityIQ certifications are focused on access and identity governance, specifically reviewing and validating user access rights within systems. Expense report certification would be a different process, typically managed by financial or expense management systems, not by IdentityIQ.
