prevent using the "Default Corporate Card Expense" type when submitting expense item amount<=zero

When user creates a expense item with greater than zero amount it is showing an error that

Error: You must include expense items in the expense report that are within the policy rate. (EXM-630493)

The same needs to be applied when user submits expense item with less than or equal to zero. Current it is accepting both the amounts.

Could anyone help in configuring this.
