Add Invoice with Payment Terms set 'Open Incoming Payment' = Cash - with DI

Question

Hi,
I have this type of problem: I have defined a Payement Terms (Payment Terms - Setup) and I have set the field 'Open Incoming Payment' = Cash.
In this way, when I create an Invoice and I put this 'Payment Terms' in Accounting Label, when I Add the Invoice, Sap open the 'Payment Means' form, and I must set the Total Cash of the payment. I set this field, click Ok, and then I'm able to Add the Invoice (and his Payment).
If I try to do this operation with DI API, when I call .Add() method, I retrieve this error: "Invoice & receipt must be paid exactly  [OINV.GroupNum]". There is a method or property in SAPbobsCOM.BoObjectTypes.oInvoices that I must set to do automatically this operation?
What can I do this???
Thank you
Marco

Hi Niall,
yes, I have set the property vInvoice.PaymentGroupCode = 2 , infact i retrive the error.
If i try to set PaymentGroupCode = 1 or PaymentGroupCode = 3 (other 'normal' Payments Terms), my procedure work correctly, and the Invoice are added.
If I try to set PaymentGroupCode = 2, i retrieve the error.
This is my simple code:
                    vInvoice.Series = 26
                    vInvoice.CardCode = "C0001"
                    vInvoice.HandWritten = SAPbobsCOM.BoYesNoEnum.tNO
                    vInvoice.DocDate = "10/01/2009"
                    vInvoice.DocType = SAPbobsCOM.BoDocumentTypes.dDocument_Service
                    vInvoice.PaymentGroupCode = 2
                    vInvoice.Lines.AccountCode = "11005010"
                    vInvoice.Lines.Quantity = 1
                    vInvoice.Lines.Currency = "Eur"
                    vInvoice.Lines.Price = 110
                    ret = vInvoice.Add()
                    If ret <> 0 Then
                        myDB.GetLastError(errCode, errMsg)
                        myapp.SetStatusBarMessage(errMsg, SAPbouiCOM.BoMessageTime.bmt_Medium, True)
                    End If
Thank
