Publish Reports with SQL Analysis Services Data in Crystal Reports

Use the Report Wizard to design a report based on up-to-date SQL Analysis Services data.

Crystal Reports has many options for offloading data processing to remote data; this enables real-time reporting. With the support for JDBC in Crystal Reports, the CData JDBC Driver for SQL Analysis Services brings this capability to Crystal Reports. This article shows how to create a report on SQL Analysis Services data that refreshes when you run the report.

Deploy the JDBC Driver

Install the CData JDBC Driver for SQL Analysis Services by including the driver JAR in the Crystal Reports classpath: Add the full file path, including the .jar, to the paths in the ClassPath element, under the DataDriverCommonElement.

The CRConfig.xml is usually located at C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\java — the path might be slightly different based on your installation. The driver JAR is located in the lib subfolder of the installation directory.

After you have added the JAR to the ClassPath, restart Crystal Reports.

Connect to SQL Analysis Services Data

After deploying the JDBC Driver for SQL Analysis Services, you can then use the Report Wizard to add SQL Analysis Services data to a new report.

  1. Click File -> New -> Standard Report.
  2. Expand the JDBC node under Create New Connection and double-click Make a New Connection.
  3. In the wizard, enter the JDBC connection URL:

    jdbc:ssas:User=myuseraccount;Password=mypassword;URL=http://localhost/OLAP/msmdpump.dll;

    To connect, provide authentication and set the Url property to a valid SQL Server Analysis Services endpoint. You can connect to SQL Server Analysis Services instances hosted over HTTP with XMLA access. See the Microsoft documentation to configure HTTP access to SQL Server Analysis Services.

    To secure connections and authenticate, set the corresponding connection properties, below. The data provider supports the major authentication schemes, including HTTP and Windows, as well as SSL/TLS.

    • HTTP Authentication

      Set AuthScheme to "Basic" or "Digest" and set User and Password. Specify other authentication values in CustomHeaders.

    • Windows (NTLM)

      Set the Windows User and Password and set AuthScheme to "NTLM".

    • Kerberos and Kerberos Delegation

      To authenticate with Kerberos, set AuthScheme to NEGOTIATE. To use Kerberos delegation, set AuthScheme to KERBEROSDELEGATION. If needed, provide the User, Password, and KerberosSPN. By default, the data provider attempts to communicate with the SPN at the specified Url.

    • SSL/TLS:

      By default, the data provider attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

    You can then access any cube as a relational table: When you connect the data provider retrieves SSAS metadata and dynamically updates the table schemas. Instead of retrieving metadata every connection, you can set the CacheLocation property to automatically cache to a simple file-based store.

    See the Getting Started section of the CData documentation, under Retrieving Analysis Services Data, to execute SQL-92 queries to the cubes.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the SQL Analysis Services JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.ssas.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    When you configure the JDBC URL, 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.

  4. Set the driver class name:

    cdata.jdbc.ssas.SSASDriver
  5. Select the tables and fields needed in the report. This example uses the Fiscal_Year and Sales_Amount columns from the Adventure_Works table.

You can then configure grouping, sorting, and summaries. For example, this article groups on Fiscal_Year and summarizes on Sales_Amount. See the following section to use the aggregate and summary to create a chart.

Create a Chart

After selecting a column to group by, the Standard Report Creation Wizard presents the option to create a chart. Follow the steps below to create a chart that aggregates the values in the Fiscal_Year column.

  1. In the Standard Report Creation Wizard, select the Bar Chart option and select the column you grouped by, Fiscal_Year in this example, in the On Change Of menu.
  2. In the Show Summary menu, select the summary you created.
  3. Select filters and a template, as needed, to finish the wizard.

Preview the finished report to view the chart, populated with your data. If you want to filter out null values, use a SelectionFormula.

Working with Remote Data

To ensure that you see updates to volatile data, click File and clear the "Save Data with Report" option. As you interact with the report, for example, drilling down to hidden details, Crystal Reports executes SQL queries to retrieve the data needed to display the report. To reload data you have already retrieved, refresh or rerun the report.

You can offload processing onto the driver by hiding details elements and enabling server-side grouping. To do this, you will need to have selected a column to group on in the report creation wizard.

  1. Click File -> Report Options and select the Perform Grouping On Server option.
  2. Click Report -> Section Expert and select the Details section of your report. Select the Hide (Drill-Down OK) option.

When you preview your report with the hidden details, Crystal Reports executes a GROUP BY query. When you double-click a column in the chart to drill down to details, Crystal Reports executes a SELECT WHERE query that decreases load times by retrieving only the data needed, instead of the entire table.
