Should not accept payment/receipt amount more than total amount

[aungzwin10]

The payment should not accept if the amount is more than total transaction amount.

There is no check for the correct amount when user do direct receipt or payment in AR/AP > Transactions or Invoice screen. Yes, it should accept partial payment(means amount less than total transaction amount) but system should alert if the amount user enter is more than the actual Due amount.

Valid condition Amount < ( Transaction Total - Paid)

I don't think that should be an absolute!

In fact, if there are multiple invoices for a customer/vendor, overpayments should be applicable to other open invoices.
