如何使用 Business Objects Web Services SDK 获取报表的 LastRunTime？

Question

我正在使用 Business Objects Web Services SDK 来访问我们的 Business Objects 数据。我已成功获取报告列表，并从中找到了之前运行过的报告的 LastSuccessfulInstance。但是，我似乎无法填充 LastRunTime 。当我执行未指定属性的查询时，它会返回为未设置，并且当我特别询问该属性时会得到相同的结果。我查看了报告本身和实例，他们都没有此信息。有谁知道我可以从哪里得到它？

这是我的代码（来自 SAP 演示之一）：

    var sessConnUrl = serviceUrl + "/session";
    var boConnection = new BusinessObjects.DSWS.Connection(sessConnUrl);
    var boSession = new Session(boConnection);

    // Setup the Enterprise Credentials used to login to the Enterprise System
    var boEnterpriseCredential = new EnterpriseCredential
                                     {
                                         Domain = cmsname,
                                         Login = username,
                                         Password = password,
                                         AuthType = authType
                                     };

    // Login to the Enterprise System and retrieve the SessionInfo
    boSession.Login(boEnterpriseCredential);


    /************************** DISPLAY INBOX OBJECTS *************************/

    // Retrieve the BIPlatform Service so it can be used to add the USER
    var biPlatformUrl = boSession.GetAssociatedServicesURL("BIPlatform");
    var boBiPlatform = BIPlatform.GetInstance(boSession, biPlatformUrl[0]);

    // Specify the query used to retrieve the inbox objects
    // NOTE: Adding a "/" at the end of the query indicates that we want to 
    //       retrieve the all the objects located directly under the inbox.
    //       Without the "/" Path operator, the inbox itself would be returned. 
    const string query = "path://InfoObjects/Root Folder/Reports/";

    // Execute the query and retrieve the reports objects
    var boResponseHolder = boBiPlatform.Get(query, null);
    var boInfoObjects = boResponseHolder.InfoObjects.InfoObject;

    // If the reports contains a list of objects, loop through and display them
    if (boInfoObjects != null) 
    {
        // Go through and display the list of documents
    foreach (var boInfoObject in boInfoObjects)
    {
            var report = boInfoObject as Webi;
            if (report == null)
                continue;

            if (!string.IsNullOrEmpty(report.LastSuccessfulInstanceCUID))
            {
                var instanceQuery = "cuid://<" + report.LastSuccessfulInstanceCUID + ">";
                var instanceResponseHolder = boBiPlatform.Get(instanceQuery, null);
                var instance = instanceResponseHolder.InfoObjects.InfoObject[0];

            }
        }
    }

report.LastRunTimeSpecified 和 instance.LastRunTimeSpecified 都是 false，并且 LastRunTime 都是 01\01\0001，但我可以在 Web Intelligence UI 中看到上次运行时间。

在 SAP 支持部门 Ted Ueda 的帮助下，我找到了答案。默认情况下，并非所有属性都会填充，您需要将 @* 附加到查询字符串才能获取所有内容，即将行：更改

const string query = "path://InfoObjects/Root Folder/Reports/";

为：

const string query = "path://InfoObjects/Root Folder/Reports/@*";
