Hi,
We are developing C# console application to call GP API. I am calling the method CreatePayablesInvoice to create payables Invoice. However I want to assign Tax lines to this.
I am trying to assign taxDetailKey to payableTax.Key.TaxDetailKey ,but am getting null object reference error. Please need help to fix this .
Below are the steps am following and I have provided the related XML also
1)// Create a payables invoice object
payablesInvoice = new PayablesInvoice();
2)// Populate the invoice properties
payablesInvoice.Key = invoiceKey;
payablesInvoice.BatchKey = batchKey;
payablesInvoice.VendorKey = vendorKey; ...etc
3)//Setting the tax lines
//Tax lines
XmlNodeList taxnodes = xmlDoc.DocumentElement.SelectNodes(xMLPMTransactionLineTaxNode);
List<PayablesTax> payableTaxes = new List<PayablesTax>();
foreach (XmlNode taxnode in taxnodes)
{
PayablesTax payableTax = new PayablesTax();
//THE BELOW TAX DETAIL ASSIGNMENT IS GIVING THE ERROR.
TaxDetailKey taxDetailKey = new TaxDetailKey();
taxDetailKey.Id = taxnode.SelectSingleNode("TAXDTLID").InnerText;
payableTax.Key.TaxDetailKey = taxDetailKey; //THIS LINE IS THROWING THE NULL OBJECT REFERENCE ERROR
MoneyAmount taxAmount = new MoneyAmount();
taxAmount.Currency = "AUD";
taxAmount.Value = Convert.ToDecimal(taxnode.SelectSingleNode("TAXAMNT").InnerText);
payableTax.TaxAmount = taxAmount;
MoneyAmount purchasetaxAmount = new MoneyAmount();
purchasetaxAmount.Currency = "AUD";
purchasetaxAmount.Value = Convert.ToDecimal(taxnode.SelectSingleNode("TDTTXPUR").InnerText);
payableTax.PurchasesTaxAmount = purchasetaxAmount;
MoneyAmount purchasetotalAmount = new MoneyAmount();
purchasetotalAmount.Currency = "AUD";
purchasetotalAmount.Value = Convert.ToDecimal(taxnode.SelectSingleNode("TXDTTPUR").InnerText);
payableTax.TotalAmount = purchasetotalAmount;
payableTaxes.Add(payableTax);
}
payablesInvoice.Taxes = payableTaxes.ToArray();
// Get the create policy for payables invoices
payablesInvoiceCreatePolicy = wsDynamicsGP.GetPolicyByOperation( "CreatePayablesInvoice", context);
// Create the payables invoice
wsDynamicsGP.CreatePayablesInvoice(payablesInvoice, context, payablesInvoiceCreatePolicy);
// Close the service
if (wsDynamicsGP.State != CommunicationState.Faulted)
{
wsDynamicsGP.Close();
}
From the above code, THE BELOW TAX DETAIL ASSIGNMENT IS GIVING THE ERROR.
TaxDetailKey taxDetailKey = new TaxDetailKey();
taxDetailKey.Id = taxnode.SelectSingleNode("TAXDTLID").InnerText;
payableTax.Key.TaxDetailKey = taxDetailKey; //THIS LINE IS THROWING THE NULL OBJECT REFERENCE ERROR
Not sure I have to use 'PayablesTax' to assign tax to PayablesInvoice?
