How can I set a minimum and maximum amount per payment method?

In RetailVista, a minimum and maximum amount can be set per payment method.
To do this, go to administration -> payment methods and open the desired payment methods.

Here, the minimum and maximum amount can be specified.
In the case of a return with a negative amount, the amount should be negative.
For example, -50 to be able to process a maximum return amount of -50 on these payment methods.
