Amount paid in currency for supplierPayment

[Maja Damber]

How can I find the amount paid to a supplier in currency? Most of the time an invoice is paid with the total amount so then I can find this out but i it is partly paid this won't be possible. I want to find out the payments effect on the accounts payable balance. 
There is a field called "balance" on the paymentLines. What will this show if the invoice is partly paid? Will this be the remaining balance in currency after the payment?

Hi, 

 "balance": 0,
  "balanceInCurrency": 0,

 fields can be checked on the Supplier Invoice for the remaining unpaid amount of the invoice. 

There is also a tab that is called "Applications" in the Supplier Invoice where we can see the applied payments and its details but unfortunately this is not exposed via the API atm.
