Connect to SAP Data in RapidMiner

Integrate SAP data with standard components and data source configuration wizards in RapidMiner Studio.

This article shows how you can easily integrate the CData JDBC driver for SAP into your processes in RapidMiner. This article uses the CData JDBC Driver for SAP to transfer SAP data to a process in RapidMiner.

Connect to SAP in RapidMiner as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to SAP:

  1. Add a new database driver for SAP: Click Connections -> Manage Database Drivers.
  2. In the resulting wizard, click the Add button and enter a name for the connection.
  3. Enter the prefix for the JDBC URL: jdbc:saperp:
  4. Enter the path to the cdata.jdbc.saperp.jar file, located in the lib subfolder of the installation directory.
  5. Enter the driver class: cdata.jdbc.saperp.SAPERPDriver
  6. Create a new SAP connection: Click Connections -> Manage Database Connections.
  7. Enter a name for your connection.
  8. For Database System, select the SAP driver you configured previously.
  9. Enter your connection string in the Host box.

    The driver supports connecting to an SAP system using the JCo JAR file. See the "Getting Started" chapter in the help documentation for information on using the Jco JAR file.

    In addition, you can connect to an SAP system using Web services (SOAP). To use Web services, you must enable SOAP access to your SAP system and set the Client, RFCUrl, User, and Password properties, under the Authentication section.

    For more information, see this guide on obtaining the connection properties needed to connect to any SAP system.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.saperp.jar

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

    A typical connection string is below:

    Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;Location=C:\\mysapschemafolder;
  10. Enter your username and password if necessary.

You can now use your SAP connection with the various RapidMiner operators in your process. To retrieve SAP data, drag the Retrieve operator from the Operators view. With the Retrieve operator selected, you can then define which table to retrieve in the Parameters view by clicking the folder icon next to the "repository entry." In the resulting Repository Browser, you can expand your connection node to select the desired example set.

Finally, wire the output to the Retrieve process to a result, and run the process to see the SAP data.
