Create SAP Business Warehouse Reports on JasperReports Server

The CData JDBC driver for SAP Business Warehouse enables you to provide access to SAP Business Warehouse data across the enterprise. This article shows how to deploy the driver on JasperReports server and create a simple report based on a reporting domain, a business view of SAP Business Warehouse data.

Deploy the Driver JAR

Follow the steps below to deploy the driver JAR on JasperReports Server. The instructions below contain specifics for SAP Business Warehouse and the Tomcat server bundled with JasperReports Server. If you are using JBoss AS 7 instead of Tomcat, you can follow the standard process to deploy the SAP Business Warehouse JDBC Driver on JBoss.

1. Copy the driver JAR and .lic file, located in the lib subfolder of the installation directory, to the lib subfolder of the apache-tomcat folder, located in the JasperReports Server installation directory.

2. Navigate to apache-tomcat -> webapps -> jasperserver-pro -> META-INF and add the following resource entry to the context.xml file:

   <Resource name="jdbc/sapbusinesswarehouse" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.sapbusinesswarehouse.SAPBusinessWarehouseDriver" url="jdbc:sapbusinesswarehouse:URL=https://mysapserver:8000;AuthScheme=Basic;User=username;Password=password;" maxActive="20" maxIdle="10" maxWait="-1" factory="com.jaspersoft.jasperserver.tomcat.jndi.JSCommonsBasicDataSourceFactory"/>
   

   Specify the required connection properties in the JDBC URL -- the url attribute.

   To connect to SAP Business Warehouse, set the URL property to a valid SAP Business Warehouse server base URL. The driver must connect to SAP Business Warehouse instances hosted over HTTP with XMLA access.

   The driver supports the following authentication schemes via the AuthScheme property:

   • None: Anonymous authentication, if available on the server.
   • Basic: Set User and Password and set AuthScheme to .
   • Kerberos: See the Using Kerberos section of the help documentation for the required Kerberos properties.

   By default, the driver 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.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.sapbusinesswarehouse.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.

3. Navigate to jasperserver-pro -> WEB-INF and add the following reference to the web.xml file:

    SAP Business Warehouse data JSP
    jdbc/sapbusinesswarehouse
    javax.sql.DataSource
    Container
   
   

4. Restart the server.

Create the SAP Business Warehouse JDBC Data Source

Follow the steps below to map the SAP Business Warehouse JDBC driver to a JDBC data source:

1. Log into JasperReports Server and click Create -> Data Source.
2. In the Type menu, select JNDI Data Source.
3. In the Service Name box, enter the JDNI lookup defined in the resource definition in the web.xml file. In the example, the lookup is "jdbc/sapbusinesswarehouse".
4. Click Save to create the Data Source.

Create a Domain

A domain is a metadata and access-control layer that surfaces a relevant business view to report creators. Follow the steps below to select SAP Business Warehouse columns, apply filters, and execute SQL to create a domain.

1. Click Create -> Domain. Enter an Id for the domain and select a save location.
2. Click Browse in the Data Source section and select the SAP Business Warehouse data source you created.
3. In the Domain Design section, click Create with Domain Designer.
4. Select the schema containing your tables.
5. On the Tables tab, select a table in the Data Source pane and then click the arrow to add them to the Selected Tables pane. 👁 Tables to add on the Tables tab in the Domain Designer. (Salesforce is shown.)
   
6. On the Derived Tables tab, you can define domains based on SQL queries. For example,

    SELECT CustomerCount, City FROM Sales WHERE Country = 'US'
    

7. On the Joins tab, you can join tables by selecting the columns you want to build the join condition and selecting the join type.
8. On the Pre-Filters tab, drag and drop columns to define search criteria that filters the data exposed through the domain.
9. On the Display tab, select SAP Business Warehouse data into the data sets presented to the user. 👁 Resources to add on the Display tab in the Domain Designer. (Salesforce is shown.)
   
10. Click OK to accept your changes and click Submit to create the domain.

Explore Data in Real Time

After you have created a domain, you are ready to connect to data. Follow the steps below to create an Ad Hoc View in the Ad Hoc Editor.

1. Click Create -> Ad Hoc View.
2. In the resulting dialog, select the SAP Business Warehouse domain you created. 👁 The domain to be used for the view. (Salesforce is shown.)
   
3. On the Choose Data page, select columns that you want to use in the view. In the Pre-Filters section, you can create filters based on the selected fields. In the Display section, you can modify column information as presented by the domain. 👁 The columns to be used in the report. (Salesforce is shown.)
   
4. After completing the wizard, select the view type and add columns to the view. JasperSoft uses the metadata of the driver to detect the available dimensions and measures, based on the data type. Drag dimensions and measures onto the Columns and Rows boxes. Right-click a measure to change the summary calculation. Drag the Columns slider to the the desired data level in the Filters section.
5. To access updates to the data as you design the view, change the menu selection from Sample Data to Full Data in the design mode toolbar. As you make changes, JasperSoft Server executes the underlying SQL queries to the driver.
6. Save the view.

Create a Real-Time Report

You can now create reports hosted on JasperSoft Server. To do so from the Ad Hoc Editor, click Save Ad Hoc View and click Create Report.
