我正在运行 RFC 以从 SAP 获取数据。当我运行这个 RFC 时，我似乎得到了一个指向数据的指针，而不是数据本身。

<ET_RETURN>BAPIRET2_</ET_RETURN>

看起来这个 BAPIRET2_ 是一些数据集名称或指针。我想要这个 BAPIRET2_ 数据集中的数据。

有什么方法可以获取数据本身吗？

SAP JCo 将使用自己的对象类型返回您的数据。您必须浏览这些对象才能获取数据。下面是一个连接到 SAP 以使用 SAP JCo 3 获取发票详细信息的 Java 方法示例。您应该注意两种返回类型：

  • “RETURN”是一种结构类型。在 java 中，这有点像 java 中的 POJO。或者您可以将其视为单个数据记录。谷歌“SAP 结构”了解更多详情。

  • “INVOICE_SUMMARIES”是一种表类型。注意for循环，它正在读取一个表格。

根据您的 RFC 的导出参数是表（它们看起来是）还是结构，您将需要调整检索数据的方式。希望这个示例足以让您入门。

private List<InvoiceSummary> getInvoices(String userId, String customerNumber, String invoiceNumber) throws InvoiceRetrievalException, JCoException {

    ArrayList<InvoiceSummary> invoices = new ArrayList<InvoiceSummary>();
    try {
        //Verify SAP connection.
        DAOFactory.registerDestination();
        JCoDestination dest = JCoDestinationManager.getDestination(DAOFactory.getDestinationName());
        JCoRepository repository = dest.getRepository();

        JCoFunctionTemplate ft = repository.getFunctionTemplate("Z_BAPI_GET_INVOICES");
        JCoFunction jFunction = ft.getFunction();

        //Set parameters.
        jFunction.getImportParameterList().setValue("USER_ID", userId);
        jFunction.getImportParameterList().setValue("CUSTOMER_NUMBER", customerNumber);
        jFunction.getImportParameterList().setValue("INVOICE_NUMBER", invoiceNumber);

        //Execute the function and read the results.
        jFunction.execute(dest);

        //Check the SAP return object for errors.
        JCoStructure out = jFunction.getExportParameterList().getStructure("RETURN");
        if ("E".equals(out.getString("TYPE"))) {
            throw new InvoiceRetrievalException(out.getString("MESSAGE"));
        }

        //Parse the returned invoices into InvoiceSummary objects.
        JCoTable invoiceTable = jFunction.getTableParameterList().getTable("INVOICE_SUMMARIES");
        for (int i = 0; i < invoiceTable.getNumRows(); i++) {
            InvoiceSummary invoice = new InvoiceSummary();
            invoiceTable.setRow(i);

            invoice.setInvoiceNumber(invoiceTable.getString("INVOICE_NUMBER"));
            invoice.setReleaseNumber(invoiceTable.getString("RELEASE_NUMBER"));
            invoice.setItemNumber(invoiceTable.getString("ITEM_NUMBER"));
            invoice.setInvoiceDate(invoiceTable.getString("INVOICE_DATE"));
            invoice.setProductDescription(invoiceTable.getString("DESCRIPTION"));
            invoice.setDueDate(invoiceTable.getString("DUE_DATE"));
            invoice.setCustomerNumber(invoiceTable.getString("CUSTOMER_NUMBER"));

            invoices.add(invoice);
        }
    } catch (InvoiceRetrievalException e) {
        logger.error("An error occurred while attempting to retrieve an invoice." +
            " userId = " + userId +
            " invoiceNumber = " + invoiceNumber, e);
        throw e;
    } catch (JCoException e) {
        logger.error("An error occurred while calling Z_BAPI_GET_INVOICES." +
            " userId = " + userId +
            " invoiceNumber = " + invoiceNumber, e);
        throw e;
    }
    return invoices;
}
