限制NetSuite返回的invoice对象数量

Question

我正在与客户的NetSuite帐户集成工作，其中包括提取发票数据，以便创建“第一个销售日期”(创建的第一个发票)和“最后的销售日期”(创建的最新发票)。我的问题涉及限制响应中返回的发票数量，因为目前在他们的系统中大约有265,000个发票记录-其中数百个可以属于一个客户记录。有没有办法只为每个客户请求两个必要的发票记录？

下面是我在C#中的当前代码：

int invoiceCount = 0;

private void searchInvoices()
{
    // This operation requires a valid session 
    this.login(true);

    TransactionSearch transactionsSearch = new TransactionSearch();
    TransactionSearchBasic transactionSearchBasic = new TransactionSearchBasic();

    transactionSearchBasic.type = new SearchEnumMultiSelectField();
    transactionSearchBasic.type.@operator = SearchEnumMultiSelectFieldOperator.anyOf;
    transactionSearchBasic.type.operatorSpecified = true;
    transactionSearchBasic.type.searchValue = new string[] { "_invoice" };

    transactionsSearch.basic = transactionSearchBasic;

    SearchResult transactionResponse = _service.search(transactionsSearch);

    Invoice[] invoices = new Invoice[transactionResponse.totalRecords];

    if (transactionResponse.status.isSuccess)
    {
        if (transactionResponse.totalRecords > 0)
        {
            for (int i = 1; i <= transactionResponse.totalPages; i++)
            {
                invoices = processTransactionSearchResponse(transactionResponse, invoices);

                if (transactionResponse.pageIndex < transactionResponse.totalPages)
                {
                    this.setPreferences();
                    this.login(true);
                    transactionResponse = _service.searchMoreWithId(transactionResponse.searchId, i + 1);

                }
            }
        }
        else
        {
            _out.info("\nNothing found.");
        }
    }
}

private Invoice[] processTransactionSearchResponse(SearchResult transResult, Invoice[] invoices)
{
    Record[] transactionRecords = transResult.recordList;
    Invoice invoice = new Invoice();

    foreach (Record rec in transactionRecords)
    {
        invoice = (Invoice)rec;
        invoices[invoiceCount] = invoice;

        invoiceCount++;
    }

    return invoices;
}
