自从更新到Cloud SDK版本2.0.0以来,我们现在遇到了向请求添加字段的问题.它主要是关于"计算实际库存凭证项目"的流程步骤.这里,项目的手动设置属性不会发送到请求中.

这些是我们实际设置并发送到S4系统的属性:

这些是嵌入在查询中的属性:

我正在尝试使用Jenkins管道中的Artifact部署阶段将工件上传到Nexus存储库.为此,我向Jenkins提供了Nexus凭据以及查找存储库的路径.但是,这个阶段失败了,错误"连接被拒绝连接".

但是,我可以在http:// localhost:8081/nexus上访问Nexus .

下面是pipeline_config.yml文件中使用的代码.

artifactDeployment:
    nexus:
      version: nexus2
      url: 'http://localhost:8081/nexus/'
      repository: myrepo
      credentialsId: 'nexus'
      additionalClassifiers:
        - type: jar
          classifier: classes

有人可以建议你解决这个问题吗？

我有一个通过调用该系统API(OData的服务)与SAP S/4HANA云(我公司的ERP系统)集成在SAP云平台Cloud Foundry的Java应用程序.我听说过SAP S/4HANA Cloud SDK,它使这些场景变得更加容易.

如何利用SAP S/4HANA Cloud SDK？目前,我调用SAP S/4HANA的代码对于检索产品主数据的方案看起来像这样(简化并连接在一起).我自己创建了这个S4Product类作为响应的表示.该baseUrl和authHeader被谈论到SAP云平台的目标服务之前确定.

StringBuilder url = new StringBuilder(baseUrl);
url.append("/sap/opu/odata/sap/API_PRODUCT_SRV/A_Product");
url.append("&$select=Product,CreationDate");
url.append("&$filter=ProductType eq '1'");
url.append("&$top=10");

URL urlObj = new URL(url.toString());
HttpURLConnection connection = (HttpURLConnection) urlObj.openConnection();
connection.setRequestMethod("GET");
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestProperty("Accept", "application/json");
connection.setRequestProperty("Authorization",authHeader);

connection.setDoInput(true);

final InputStreamReader in = new InputStreamReader(connection.getInputStream());
String response = CharStreams.toString(in);

List<S4Product> result = Arrays.asList(new Gson().fromJson(response, S4Product[].class));

现在我被要求与商业伙伴做类似的事情.如何使用SDK 为业务合作伙伴OData服务执行此操作？如果我想使用SDK,是否必须创建新的应用程序？

作为PoC的一部分,我目前正在尝试为S/4HANA Cloud的并行扩展构建原型,包括两个层:使用S/4HANA Cloud SDK与Java后端分离的SAPUI5前端.

总的来说它也很棒.但是我经常遇到UPDATE命令的问题,所以我为了演示目的编写了一个小的servlet.现在,我总是在更新期间得到相同的异常,即"解析元数据时出错".

我已经尝试了一切,现在不知道这个异常的触发器是什么.

我试图在pom.xml中添加更多依赖项,但这没有成功.尝试使用GET命令获取所有字段并更新填充的对象也是不成功的.ETag也不是问题,这是自"versionIdentifier"最新发布以来的优秀处理.

如果你们其中一个人知道我的错误在哪里,我将非常感激!

在此先感谢您的帮助!

[OLD] Code Snippet:公共类UpdateService扩展了HttpServlet

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

    // Test-Run: UPDATE
    response.getWriter().write("Test-Run: UPDATE" + "\n");

    // Prepare the S/4HANA Cloud Service
    DefaultSalesOrderService service = new DefaultSalesOrderService();

    // Prepare the required Variables
    String salesOrderKey = "1";
    String deliveryBlockReason = "01";
    SalesOrder salesOrder;

    try {

        // Get the Sales Order
        response.getWriter().write("Step 1: Get old data.." + "\n");
        salesOrder = service.getSalesOrderByKey(salesOrderKey).select(SalesOrder.DELIVERY_BLOCK_REASON).execute();

我正在尝试使用VDM从使用VDM的S/4HANA Cloud 1805系统读取数据,如https://blogs.sap.com/2017/05/21/step-4-with-sap-中所述s4hana-cloud-sdk-calling-an-odata-service /.目标使用基本身份验证.

示例电话:

final ErpConfigContext context = new ErpConfigContext("...");
return new DefaultQualityInspectionDataService().getAllInspectionLot().select(...).execute(context);

这至少在S/4HANA Cloud SDK版本1.9.4之前有效.由于更新到2.0.0,由于以下异常,目标无法再使用:

为CF添加这样的云SDK: compile "com.sap.cloud.s4hana:s4hana-all:${cloudSDKVersion}" compile ("com.sap.cloud.s4hana.cloudplatform:scp-cf:${cloudSDKVersion}") 导致弹簧启动jar中的重复jar,它被部署到CF. 例子: core-2.3.1.jar connectivity-2.3.1.jar

• 这导致 :
  • 运行时期间的ClassNotFoundExceptions
  • 防止cf push命令出错: Comparing local files to remote cache... Aborting push: File BOOT-INF/lib/core-2.3.1.jar has been modified since the start of push. Validate the correct state of the file and try again. FAILED

我想知道如何远程调试部署在 SAP Cloud Foundry 中的 S4SDK/Spring 2.0.6 Java 应用程序。

我正在使用 Eclipse（Spring Tool Suite）并在调试模式下启动应用程序。应用程序将使用以下环境变量重新启动： -Dspring.devtools.remote.secret=secret -Xdebug -Xrunjdwp:server=y,transport=dt_socket,suspend=n,address=47822

控制台输出显示，启动后 SSH 隧道已自动创建成功（作为先决条件，我已使用 cf enable-ssh 启用了 SSH）。和“10.0.136.5:34858 的成功远程访问”。

几秒钟后，eclipse 显示消息“无法连接到远程 VM”。

如何启用远程调试？

用于执行呼叫的目的地被配置为认证类型为oAuth2SAMLBearerAssertion,业务用户已经在系统中具有用户ID,电子邮件和其他基本详细信息.从SDK调用execute方法我得到以下错误:

Caused by: com.sap.cloud.sdk.cloudplatform.connectivity.exception.DestinationAccessException: Failed to get authentication headers. Destination service returned error: Provided authorization grant is invalid. Exception was No user found with alias 'name@domain.com' (format: unspecified).

我正在尝试使用VDM从我们的S/4HANA云(公共云)获取业务合作伙伴数据.

        final List<BusinessPartner> businessPartners =
                new DefaultBusinessPartnerService()
                        .getAllBusinessPartner()
                        .select(BusinessPartner.BUSINESS_PARTNER,
                                BusinessPartner.BUSINESS_PARTNER_NAME)
                        .filter(BusinessPartner.BUSINESS_PARTNER_CATEGORY.eq("2"))
                        .orderBy(BusinessPartner.BUSINESS_PARTNER, Order.ASC)
                        .execute();

正确显示英文业务伙伴名称.但日本商业伙伴名称显示为?????.

{"BusinessPartner":"80000001","BusinessPartnerName":"Domestic US Customer 1"},
{"BusinessPartner":"80000002","BusinessPartnerName":"?????????????"},
{"BusinessPartner":"90000001","BusinessPartnerName":"Domestic US Supplier 1"},
{"BusinessPartner":"90000002","BusinessPartnerName":"????????"}

你能给我建议如何获取本地化字段的文本吗？

谢谢.

(补充说明)

我用Postman手动执行了OData.在这种情况下,本地化字段以日语显示.

但是每次我在WebIDE中检查服务时，都会出现错误500。
