Outgoing cash payments on creditnotes

Question

Hi there.
Does anyone know how to make outgoing payments linked to a creditnote in DI Server? (or at the very least in DI Api?)
oIncomingPayments has the Payments_Invoices, that is great for registering payments on an invoice, but I haven't found a way to do the same for a creditnote.
And I cannot use the oVendorPayments, because the customers in question are not vendors.
I should think that pay out cash on a creditnote should be a simple thing to do,
but I am at a loss here.
I'm writing a cash counter application, so the users don't have access to the SAP UI.

Answer 1

Thanx a lot, it always worked like a dream!
However, it didn't work as it should.
What I want to do, is create a creditnote, and pay the sum out to the customer in cash, eg when something he bought was defect.
If I create a creditnote, say with a doctotal of 1000, the customers balance is then increased to 1000. I then add payment as you said. The creditnote is now closed, its Paid/Credited field is set to the total amount, and the Credit Balance is zero. Everything looks great. Until I have a look at the customer balance. It is now increased to 2000! Instead of being done with the customer after paying him, it looks like we owe him twice as much!
I've tried reversing the amounts, but just get the "Amount must be positive" error message etc.
And setting SumApplied to positive gives the 'Payment amount is greater than invoice amount'
Here is the xml:
<?xml version="1.0" encoding="UTF-16"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<env:Header>
<SessionID>B57AA457-10AA-19B8-8F3B-ABE41D6325C5</SessionID>
</env:Header>
<env:Body>
<dis:AddObject xmlns:dis="http://www.sap.com/SBO/DIS">
<BOM>
<BO>
<AdmInfo>
<Object>oIncomingPayments</Object>
</AdmInfo>
<Payments>

<CardCode>100000</CardCode>
<CashSum>2331.0</CashSum>

</Payments>
<Payments_Invoices>

<InvoiceType>it_CredItnote</InvoiceType>
</row>
</Payments_Invoices>
</BO>
</BOM>
</dis:AddObject>
</env:Body>
</env:Envelope>
I also tried adding <DocObjectCode>bopot_OutgoingPayments</DocObjectCode> to signal that this is an <b>outgoing</b> payment, but then I only got
'46' is not a valid value for field 'ObjType'. The valid values are: '24' - 'Incoming Payment'
[edit]
Hm, I think maybe the trick is to use oVendorPayments instead of oIncomingPayments, but havent' found out how to signal that it is a customer, and not a vendor, so I only get 'Busines partner type does not match document.'
