基本步骤：

  1. 使用SSRS建立报表，以下的例子是以记录的GUID作为报表的参数
  2. 获取ReportSession 和 ControlId来调用报表
  3. 以PDF的形式预览报表

一、根据报表的名称获取报表的GUID

//use sdk.soap java script library to fetch record.

  getReportGuidByName:function(reportName) {

         var fetchXml = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>" +

                            "<entity name='report'>" +

                            "<attribute name='name' />" +

                            "<attribute name='reporttypecode' /> " +

                            "<attribute name='filename' /> " +

                            "<attribute name='reportid' />" +

                             "<filter type='and'>" +

                                "<condition attribute='name' operator='eq' value='" + reportName + "' />" +

                             "</filter>" +

                            "</entity>" +

                        "</fetch>"

         var fetchQuery = new Sdk.Query.FetchExpression(fetchXml);

         var results = Sdk.Sync.retrieveMultiple(fetchQuery);

         return results.view().entities[0].attributes.reportid.fValue;

     }

二、取得报表的 SessionID 和 ControlID。

//Method to get the SessionID and ControlID for the SSRSReport

getReportingSession: function () { 

    var selectedIds = Xrm.Page.data.entity.getId();

    var reportName = "<NameofReport.rdl>";

    var reportGuid = getReportGuidByName(reportName); //OR Report GUID - Replace with your report GUID

    var pth = Xrm.Page.context.getClientUrl() + "/CRMReports/rsviewer/QuirksReportViewer.aspx";

    var retrieveEntityReq = new XMLHttpRequest();

    retrieveEntityReq.open("POST", pth, false);

    retrieveEntityReq.setRequestHeader("Accept", "*/*");

    retrieveEntityReq.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");

    retrieveEntityReq.send("id=%7B" + reportGuid + "%7D&uniquename=" + Xrm.Page.context.getOrgUniqueName() + "&iscustomreport=true&reportnameonsrs=&reportName=" + reportName + "&isScheduledReport=false&p:parameterNamespecified in ssrs report=" + selectedIds);

    var x = retrieveEntityReq.responseText.lastIndexOf("ReportSession="); var y = retrieveEntityReq.responseText.lastIndexOf("ControlID=");

    var ret = new Array();

    ret[0] = retrieveEntityReq.responseText.substr(x + 14, 24); ret[1] = retrieveEntityReq.responseText.substr(x + 10, 32);

    return ret; 

}

三、生成PDF报表并在新的窗口打开

//Method to Download PDF.

runReportToPrint: function () {

    var params = getReportingSession();

    var newPth = Xrm.Page.context.getClientUrl() + "/Reserved.ReportViewerWebControl.axd?ReportSession=" + params[0] + "&Culture=1033&CultureOverrides=True&UICulture=1033&UICultureOverrides=True&ReportStack=1&ControlID=" + params[1] + "&OpType=Export&FileName=public&ContentDisposition=OnlyHtmlInline&Format=PDF";

    window.open(newPth, "_self");

 }
