3824329 - What's the system logic to adjust meal allowance when travel allowance set 'Actual expenses up to allowed limit'?

We use 'Actual expenses up to allowed limit' for meal travel allowance. If one user claim multiple meals in one day and they're over-limited, how system adjust each line's amount?
Will system keep the first line and cut off the second line?
