We are using Interop.QBFC14 SDK to delete invoice.
IMsgSetRequest requestMsgSet = sessionHelper.GetMsgSetRequest();
ITxnDel txnDelRq = requestMsgSet.AppendTxnDelRq();
txnDelRq.TxnDelType.SetValue(ENTxnDelType.tdtInvoice);
txnDelRq.TxnID.SetValue("<<InvoiceNo>>");
But the response from SDK is
Object "[[InvoiceNo]]" specified in the request cannot be found.
IMsgSetRequest requestMsgSet = sessionHelper.GetMsgSetRequest();
ITxnDel txnDelRq = requestMsgSet.AppendTxnDelRq();
txnDelRq.TxnDelType.SetValue(ENTxnDelType.tdtInvoice);
txnDelRq.TxnID.SetValue(TxnID);
Pass TxnID
