Approval rules are prioritised from top to bottom, with Rule #1 having the highest priority and the Fallback rule having the lowest priority. The system only uses the first rule that matches, so place more complex rules at the top and general ones at the bottom.
Bill payment, reimbursement and top-up request approval rules will have a 'Fallback rule' by default. All of these approval types must always require some level of approval.
For card expense approval types, the default is that no approval is required.
