Connect to SAP Data in the Denodo Platform

Denodo Platform is a data virtualization product providing a single point of contact for enterprise database data. When paired with the CData JDBC Driver for SAP ERP, Denodo users can work with live SAP data alongside other enterprise data sources. This article walks through creating a virtual data source for SAP in the Denodo Virtual DataPort Administrator.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live SAP data. When you issue complex SQL queries to SAP, the driver pushes supported SQL operations, like filters and aggregations, directly to SAP and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze SAP data using native data types.

Create the SAP Virtual Port

To connect to live SAP data from Denodo, you need to copy the JDBC Driver JAR file to the external library directory for Denodo and create a new JDBC Data Source from the Virtual DataPort Administrator tool.

1. Download the CData JDBC Driver for SAP ERP installer, unzip the package, and run the JAR file to install the driver.
2. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for SAP ERP\lib\) to the Denodo external library directory (C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-saperp-19).
3. Open the Denodo Virtual DataPort Administrator tool and navigate to the Server Explorer tab.
4. Right-click "admin" and select New -> Data source -> JDBC.
5. Configure the JDBC Connection:
   • Name: your choice, e.g.: saperp
   • Database adapter: Generic
   • Driver class path: C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-saperp-19
   • Driver class: cdata.jdbc.saperp.SAPERPDriver

   • Database URI: Set this to a JDBC URL using the necessary connection properties. For example,

     jdbc:saperp:Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;Location=C:/mysapschemafolder;

     Information on creating the Database URI follows:

     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.

     The driver supports connecting to an SAP system using the SAP Java Connector (SAP JCo). Install the files (sapjco3.jar and sapjco3.dll) to the appropriate directory for the hosting application or platform. See the "Getting Started" chapter in the help documentation for information on using the SAP JCo files.

     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.

6. Click the "Test connection" button to confirm the configuration and click Save.

View SAP Data in the VirtualPort Administrator Tool

After creating the data source, you can create a base view of SAP data for use in the Denodo Platform.

1. Click the "Create base view" button in the newly created VirtualPort (admin.SAPERP).
2. Expand the object tree and select the objects (tables) you wish to import.
3. Click the "Create selected" button to create views of the SAP data.
   Optional: Click "Create associations from foreign keys" to define relationships between the objects.
4. With the view(s) created, navigate to a table (cdata_saperp_mara) in the Server Explorer and double-click the selected table.
5. In the new tab, click "Execution panel" to open a query panel.
6. Customize the query in the "Execute" tab or use the default:

   SELECT * FROM cdata_saperp_mara CONTEXT ('i18n'='us_est', 'cache_wait_for_load'='true')
   

7. Click Execute to view the data.

With the base view created, you can now work with live SAP data like you would any other data source in Denodo Platform, for example, querying SAP in the Denodo Data Catalog.
