Connect to SAP Data in CloverETL

Transfer SAP data using the visual workflow in the CloverETL data integration tool.

The CData JDBC Driver for SAP enables you to use the data transformation components in CloverETL to execute queries to SAP data. In this article, you will use the JDBC Driver for SAP to set up a simple transfer into a flat file.

Connect to SAP as a JDBC Data Source

  1. Create the connection to SAP data. In a new CloverETL graph, right-click the Connections node in the Outline pane and click Connections -> Create Connection. The Database Connection wizard is displayed.
  2. Click the plus icon to load a driver from a JAR. Browse to the lib subfolder of the installation directory and select the cdata.jdbc.saperp.jar file.
  3. Enter the JDBC URL. A typical JDBC URL is below: jdbc:saperp:Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;Location=C:\\mysapschemafolder;

    You can connect to SAP systems using either librfc32.dll, librfc32u.dll, NetWeaver, or Web Services (SOAP). Set the ConnectionType connection property to CLASSIC (librfc32.dll), CLASSIC_UNICODE (librfc32u.dll), NETWEAVER, or SOAP.

    If you are using the SOAP interface, set the Client, RFCUrl, SystemNumber, User, and Password properties, under the Authentication section.

    Otherwise, set Host, User, Password, Client, and SystemNumber.

    Note: We do not distribute the librfc32.dll or other SAP assemblies. You must find them from your SAP installation and install them on your machine.

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

Query SAP Data with the DBInputTable Component

  1. Drag a DBInputTable from the Readers selection of the Palette onto the job flow and double-click it to open the configuration editor.
  2. In the DB connection property, select the SAP JDBC data source from the drop-down menu.
  3. Enter the SQL query. For example: SELECT * FROM MARA

Write the Output of the Query to a UniversalDataWriter

  1. Drag a UniversalDataWriter from the Writers selection onto the jobflow.
  2. Double-click the UniversalDataWriter to open the configuration editor and add a file URL.
  3. Right-click the DBInputTable and then click Extract Metadata.
  4. Connect the output port of the DBInputTable to the UniversalDataWriter.
  5. In the resulting Select Metadata menu for the UniversalDataWriter, choose the MARA table. (You can also open this menu by right-clicking the input port for the UniversalDataWriter.)
  6. Click Run to write to the file.
