3819293 - How Do I Prevent Users from Creating Expense Reports?

I need a way to prevent a user from being able to create an expense report. How do I do this?

I have an audit rule to prevent users from submitting expense reports if there is no Vendor ID assigned in their profile, but I would like to know if they can be prevented from creating expense reports if they don't have a Vendor ID assigned. , KBA , CON-CA-CMP-ACP , Administer Company Permissions , Problem
