Incoming Payment

Hi,

Ok Here's the scenario :

I do create an Invoice of $522.46. from the DI API

The client do it in 2 kind of payment, one of $250 and one of $300

Now since the Incoming Payment needs to be the exact DocTotal of the Invoice,

In which property do I set the refund of 27.54 so the Incoming Payment can accept the 2 payments ?

I'm asking because when I try to create the Incoming Payments for this invoice

hence : oIncomingPayments.Invoices.SumApplied and add the 2 payments, it doesn't accept it. But if the sum of the 2 payments equal de DocTotal of the invoice, it works.

Thank you for you support
