ETL SAP Ariba Procurement in Oracle Data Integrator



This article shows how to transfer SAP Ariba Procurement data into a data warehouse using Oracle Data Integrator.

Leverage existing skills by using the JDBC standard to connect to SAP Ariba Procurement: Through drop-in integration into ETL tools like Oracle Data Integrator (ODI), the CData JDBC Driver for SAP Ariba Procurement connects real-time SAP Ariba Procurement data to your data warehouse, business intelligence, and Big Data technologies.

JDBC connectivity enables you to work with SAP Ariba Procurement just as you would any other database in ODI. As with an RDBMS, you can use the driver to connect directly to the SAP Ariba Procurement APIs in real time instead of working with flat files.

This article walks through a JDBC-based ETL -- SAP Ariba Procurement to Oracle. After reverse engineering a data model of SAP Ariba Procurement entities, you will create a mapping and select a data loading strategy -- since the driver supports SQL-92, this last step can easily be accomplished by selecting the built-in SQL to SQL Loading Knowledge Module.

Install the Driver

To install the driver, copy the driver JAR (cdata.jdbc.saparibaprocurement.jar) and .lic file (cdata.jdbc.saparibaprocurement.lic), located in the installation folder, into the ODI appropriate directory:

  • UNIX/Linux without Agent: ~/.odi/oracledi/userlib
  • UNIX/Linux with Agent: ~/.odi/oracledi/userlib and $ODI_HOME/odi/agent/lib
  • Windows without Agent: %APPDATA%\Roaming\odi\oracledi\userlib
  • Windows with Agent: %APPDATA%\odi\oracledi\userlib and %APPDATA%\odi\agent\lib

Restart ODI to complete the installation.

Reverse Engineer a Model

Reverse engineering the model retrieves metadata about the driver's relational view of SAP Ariba Procurement data. After reverse engineering, you can query real-time SAP Ariba Procurement data and create mappings based on SAP Ariba Procurement tables.

  1. In ODI, connect to your repository and click New -> Model and Topology Objects.
  2. On the Model screen of the resulting dialog, enter the following information:
    • Name: Enter SAPAribaProcurement.
    • Technology: Select Generic SQL (for ODI Version 12.2+, select Microsoft SQL Server).
    • Logical Schema: Enter SAPAribaProcurement.
    • Context: Select Global.
  3. On the Data Server screen of the resulting dialog, enter the following information:
    • Name: Enter SAPAribaProcurement.
    • Driver List: Select Oracle JDBC Driver.
    • Driver: Enter cdata.jdbc.saparibaprocurement.SAPAribaProcurementDriver
    • URL: Enter the JDBC URL containing the connection string.

      In order to connect with SAP Ariba Procurement, set the following:

      • ANID: Your Ariba Network ID.
      • ANID: Specify which API you would like the provider to retrieve SAP Ariba data from. Select the Buyer or Supplier API based on your business role (possible values are PurchaseOrdersBuyerAPIV1 or PurchaseOrdersSupplierAPIV1).
      • Environment: Indicate whether you are connecting to a test or production environment (possible values are TEST or PRODUCTION).

      Authenticating with OAuth

      After setting connection properties, you need to configure OAuth connectivity to authenticate.

      • Set AuthScheme to OAuthClient.
      • Register an application with the service to obtain the APIKey, OAuthClientId and OAuthClientSecret.

        For more information on creating an OAuth application, refer to the Help documentation.

      Automatic OAuth

      After setting the following, you are ready to connect:

        APIKey: The Application key in your app settings. OAuthClientId: The OAuth Client Id in your app settings. OAuthClientSecret: The OAuth Secret in your app settings.

      When you connect, the provider automatically completes the OAuth process:

      1. The provider obtains an access token from SAP Ariba and uses it to request data.
      2. The provider refreshes the access token automatically when it expires.
      3. The OAuth values are saved in memory relative to the location specified in OAuthSettingsLocation.

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.saparibaprocurement.jar

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

      Below is a typical connection string:

      jdbc:saparibaprocurement:ANID=AN02000000280;API=PurchaseOrdersBuyerAPI-V1;APIKey=wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU;AuthScheme=OAuthClient;InitiateOAuth=GETANDREFRESH
  4. On the Physical Schema screen, enter the following information:
    • Name: Select from the Drop Down menu.
    • Database (Catalog): Enter CData.
    • Owner (Schema): If you select a Schema for SAP Ariba Procurement, enter the Schema selected, otherwise enter SAPAribaProcurement.
    • Database (Work Catalog): Enter CData.
    • Owner (Work Schema): If you select a Schema for SAP Ariba Procurement, enter the Schema selected, otherwise enter SAPAribaProcurement.
  5. In the opened model click Reverse Engineer to retrieve the metadata for SAP Ariba Procurement tables.

Edit and Save SAP Ariba Procurement Data

After reverse engineering you can now work with SAP Ariba Procurement data in ODI. To view SAP Ariba Procurement data, expand the Models accordion in the Designer navigator, right-click a table, and click View data.

Create an ETL Project

Follow the steps below to create an ETL from SAP Ariba Procurement. You will load Orders entities into the sample data warehouse included in the ODI Getting Started VM.

  1. Open SQL Developer and connect to your Oracle database. Right-click the node for your database in the Connections pane and click new SQL Worksheet.

    Alternatively you can use SQLPlus. From a command prompt enter the following:

    sqlplus / as sysdba
  2. Enter the following query to create a new target table in the sample data warehouse, which is in the ODI_DEMO schema. The following query defines a few columns that match the Orders table in SAP Ariba Procurement: CREATE TABLE ODI_DEMO.TRG_ORDERS (REVISION NUMBER(20,0),DocumentNumber VARCHAR2(255));
  3. In ODI expand the Models accordion in the Designer navigator and double-click the Sales Administration node in the ODI_DEMO folder. The model is opened in the Model Editor.
  4. Click Reverse Engineer. The TRG_ORDERS table is added to the model.
  5. Right-click the Mappings node in your project and click New Mapping. Enter a name for the mapping and clear the Create Empty Dataset option. The Mapping Editor is displayed.
  6. Drag the TRG_ORDERS table from the Sales Administration model onto the mapping.
  7. Drag the Orders table from the SAP Ariba Procurement model onto the mapping.
  8. Click the source connector point and drag to the target connector point. The Attribute Matching dialog is displayed. For this example, use the default options. The target expressions are then displayed in the properties for the target columns.
  9. Open the Physical tab of the Mapping Editor and click ORDERS_AP in TARGET_GROUP.
  10. In the ORDERS_AP properties, select LKM SQL to SQL (Built-In) on the Loading Knowledge Module tab.

You can then run the mapping to load SAP Ariba Procurement data into Oracle.
