Publish Crystal Reports on Adobe Target Data

The CData ADO.NET Provider for Adobe Target is fully integrated into the SAP Crystal Reports for Visual Studio development environment. You can employ standard ADO.NET components to construct reports, much like you would with SQL Server, but with the added advantage of real-time connectivity to Adobe Target. This article will guide you through the essential three steps to incorporate Adobe Target data into a report that refreshes upon opening.

Note: You will need to install SAP Crystal Reports, developer version for Visual Studio to follow this tutorial.

Create a Crystal Reports Application

To follow this article, you will also need a Visual Studio Crystal Reports project. This article will add a report to a WPF application. You can create one by clicking File -> New Project and then selecting the Crystal Reports WPF Application template. In the resulting wizard, select the option to create a blank report.

Connect to Adobe Target

Creating an ADO.NET data source for Adobe Target from Server Explorer makes it easy to create a DataSet that can be used in Crystal Reports wizards and the Crystal Reports Designer. You can find a guide to working with Adobe Target data in Server Explorer in the "Getting Started" chapter of the help documentation.

To connect to Adobe Target, you must provide the Tenant property along with OAuth connection properties mentioned below. Note that while other connection properties can influence processing behavior, they do not affect the ability to connect.

To determine your Tenant name:

1. Log in to Adobe Experience. The URL will look similar to: "https://experience.adobe.com/#/@mycompanyname/preferences/general-section".
2. Extract the value after the "/#/@". In this example, it is "mycompanyname".
3. Set the Tenant connection property to that value.

User Accounts (OAuth)

You must set AuthScheme to OAuthClient for all user account flows.

Note: Adobe authentication via OAuth requires updating your token every two weeks.

All Applications

CData provides an embedded OAuth application that simplifies OAuth authentication. Alternatively, you can create a custom OAuth application. Review Creating a Custom OAuth App in the Help documentation for more information.

Obtaining the OAuth Access Token

Set the following properties to connect:

• InitiateOAuth: Set to GETANDREFRESH to automatically perform the OAuth exchange and refresh the OAuthAccessToken as needed.
• OAuthClientId : Set to the client Id assigned when you registered your app.
• OAuthClientSecret : Set to the client secret assigned when you registered your app.
• CallbackURL : Set to the redirect URI defined when you registered your app. For example: https://localhost:3333

With these settings, the provider obtains an access token from Adobe Target, which it uses to request data. The OAuth values are stored in the location specified by OAuthSettingsLocation, ensuring they persist across connections.

When you configure the connection, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Create a DataSet

Follow the steps below to use the Visual Studio ADO.NET DataSet Designer to create an ADO.NET DataSet object. Crystal Reports will bind to the DataSet object, which contains Adobe Target table metadata. Note that this approach also adds a connection string to App.config; you will use this connection string later to load data into the report.

1. In the Solution Explorer, right-click your project and then click Add -> New Item.
2. Select DataSet. The DataSet Designer is then displayed.
3. Drag and drop tables from Server Explorer onto the DataSet Designer. This article uses the Activities table.

Add Adobe Target Fields to the Report

Follow the steps below to add columns from the DataSet to the report:

1. Double-click the .rpt file in the Solution Explorer to open the Crystal Reports Designer.
2. Right-click the designer and click Database -> Database Expert.
3. Expand the Project Folder and ADO.NET DataSets nodes and drag the DataSet you created into the Selected Tables box. The fields are now accessible from the Field Explorer.
4. Drag and drop fields from the Field Explorer to the Details section or another section of your report.

Load Data into the Report

Having created the DataSet, which will only contain the metadata, you will now need to create the DataTable containing the actual data. You can use the AdobeTargetDataAdapter to fill a DataTable with the results of an SQL query.

1. Add a reference to System.Configuration.dll to your project to be able to use the connection string from App.config.
2. In App.config, add the following code to the configuration node for compatibility with Crystal Reports when working with .NET 4.0:

    <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
    </startup>
   

3. Add the following references in your Window.xaml.cs file:

   using System.Configuration;
   using CrystalDecisions.CrystalReports.Engine;
   using CrystalDecisions.Shared;
   using System.Data.CData.AdobeTarget;
   using System.Data;
   

4. Add the following Window_Loaded method in your Window.xaml.cs to execute the SQL query that will return the DataTable. Note that your query needs to select at least the same columns used in your report.

   private void Window_Loaded(object sender, RoutedEventArgs e) {
    ReportDocument report = new ReportDocument();
    report.Load("../../CrystalReport1.rpt"); 
    var connectionString = ConfigurationManager.ConnectionStrings["MyAppConfigConnectionStringName"].ConnectionString;
    using (AdobeTargetConnection connection = new AdobeTargetConnection(connectionString)) {
    AdobeTargetDataAdapter dataAdapter = new AdobeTargetDataAdapter(
    "SELECT Id, Name FROM Activities WHERE Type = 'AB'", connection);
    DataSet set = new DataSet("_set");
    DataTable table = set.Tables.Add("_table");
    dataAdapter.Fill(table);
    report.SetDataSource(table);
    }
    reportViewer.ViewerCore.ReportSource = report;
   }
   

5. In the Window.xaml file, add the Loaded event so that your Window tag resembles the following:

   <Window x:Class="CrystalReportWpfApplication4.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:cr="clr-namespace:SAPBusinessObjects.WPF.Viewer;assembly=SAPBusinessObjects.WPF.Viewer"
    Title="WPF Crystal Report Viewer" Height="600" Width="800" Loaded="Window_Loaded">
    ...
   </Window>
   

6. Run the report. When the report is loaded, the provider executes the query to retrieve the current data. 👁 A report that loads the current data when opened. (Salesforce is shown.)
   

Chart Adobe Target Data

You can also use the DataSet with experts like the Chart Expert:

1. Right-click in the Crystal Reports Designer and click Insert -> Chart.
2. Select the Report Header or Report Footer section. The Chart Expert is then displayed.
3. On the Type tab, select the chart type. This article uses a side-by-side bar chart.
4. On the Data tab, select the column and conditions for the x-axis. For example, drag the Id column in the DataSet node onto the box under the On Change Of menu.
5. Select the x-axis column and click the TopN and Order buttons to configure sorting and limiting.
6. Select the columns and summary operations for the y-axis. For example, drag the Name column in the DataSet node into the Show Values box.
7. Run the report.

Note that Crystal Reports performs the aggregation on the data already loaded into DataTable, instead of, for example, executing a GROUP BY to the Adobe Target API. This will also be true for the report creation wizards.

You could gain more control over the queries executed to Adobe Target by creating another DataSet and populating it with a different query. See the help documentation for more information on the driver's SQL engine.
