qbfc/qbxml ReceivePaymentAdd assign Payment to Invoice - sdk

Question

When I try to associate a Payment with an Invoice, I get the following error:
ReceivePaymentAdd
ORApplyPayment:
OR object has multiple values
End of ORApplyPayment
End of ReceivePaymentAdd
What does that error mean? How do I get this to work?
Note that I am pushing the Invoice into QuickBooks in a separate session, so I cannot use Macros. If I use IsAutoApply true without the AppliedToTxnAdd block, the payment pushes just fine.
Here is the generated xml:
<?xml version="1.0" encoding="utf-8"?>
<?qbxml version="10.0"?>
<QBXML>
<QBXMLMsgsRq onError = "continueOnError">
<ReceivePaymentAddRq requestID = "0">

Answer 1

This:
ORApplyPayment:
OR object has multiple values
End of ORApplyPayment
Means that the specification (see the QuickBooks OSR) specifies that you can use EITHER AppliedToTxnAdd OR you can use IsAutoApply, but you may not use both of them. You can use one, OR the other.
You're using both, so you're getting an error message. Either remove <IsAutoApply> or remove your <AppliedToTxnAdd> tag.
Here's an example for you:
