SAP Ariba Source Icon SAP Ariba Source ODBC Driver

The SAP Ariba Source ODBC Driver is a powerful tool that allows you to connect with live data from SAP Ariba Source, directly from any applications that support ODBC connectivity.

Access SAP Ariba Source data like you would a database - read, write, and update SAP Ariba Source 0, etc. through a standard ODBC Driver interface.

Analyze SAP Ariba Source Data in R


Create data visualizations and use high-performance statistical functions to analyze SAP Ariba Source data in Microsoft R Open.

Access SAP Ariba Source data with pure R script and standard SQL. You can use the CData ODBC Driver for SAP Ariba Source and the RODBC package to work with remote SAP Ariba Source data in R. By using the CData Driver, you are leveraging a driver written for industry-proven standards to access your data in the popular, open-source R language. This article shows how to use the driver to execute SQL queries to SAP Ariba Source data and visualize SAP Ariba Source data in R.

Install R

You can complement the driver's performance gains from multi-threading and managed code by running the multithreaded Microsoft R Open or by running R linked with the BLAS/LAPACK libraries. This article uses Microsoft R Open (MRO).

Connect to SAP Ariba Source as an ODBC Data Source

Information for connecting to SAP Ariba Source follows, along with different instructions for configuring a DSN in Windows and Linux environments.

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

  • API: Specify which API you would like the provider to retrieve SAP Ariba data from. Select the Supplier, Sourcing Project Management, or Contract API based on your business role (possible values are SupplierDataAPIWithPaginationV4, SourcingProjectManagementAPIV2, or ContractAPIV1).
  • DataCenter: The data center where your account's data is hosted.
  • Realm: The name of the site you want to access.
  • Environment: Indicate whether you are connecting to a test or production environment (possible values are TEST or PRODUCTION).

If you are connecting to the Supplier Data API or the Contract API, additionally set the following:

  • User: Id of the user on whose behalf API calls are invoked.
  • PasswordAdapter: The password associated with the authenticating User.

If you're connecting to the Supplier API, set ProjectId to the Id of the sourcing project you want to retrieve data from.

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.

When you configure the DSN, 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.

Windows

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Linux

If you are installing the CData ODBC Driver for SAP Ariba Source in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData SAPAribaSource Source] Driver = CData ODBC Driver for SAP Ariba Source Description = My Description API = SupplierDataAPIWithPagination-V4 APIKey = wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU Environment = SANDBOX Realm = testRealm AuthScheme = OAuthClient

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Load the RODBC Package

To use the driver, download the RODBC package. In RStudio, click Tools -> Install Packages and enter RODBC in the Packages box.

After installing the RODBC package, the following line loads the package:

library(RODBC)

Note: This article uses RODBC version 1.3-12. Using Microsoft R Open, you can test with the same version, using the checkpoint capabilities of Microsoft's MRAN repository. The checkpoint command enables you to install packages from a snapshot of the CRAN repository, hosted on the MRAN repository. The snapshot taken Jan. 1, 2016 contains version 1.3-12.

library(checkpoint) checkpoint("2016-01-01")

Connect to SAP Ariba Source Data as an ODBC Data Source

You can connect to a DSN in R with the following line:

conn <- odbcConnect("CData SAPAribaSource Source")

Schema Discovery

The driver models SAP Ariba Source APIs as relational tables, views, and stored procedures. Use the following line to retrieve the list of tables:

sqlTables(conn)

Execute SQL Queries

Use the sqlQuery function to execute any SQL query supported by the SAP Ariba Source API.

vendors <- sqlQuery(conn, "SELECT SMVendorID, Category FROM Vendors WHERE Region = 'USA'", believeNRows=FALSE, rows_at_time=1)

You can view the results in a data viewer window with the following command:

View(vendors)

Plot SAP Ariba Source Data

You can now analyze SAP Ariba Source data with any of the data visualization packages available in the CRAN repository. You can create simple bar plots with the built-in bar plot function:

par(las=2,ps=10,mar=c(5,15,4,2)) barplot(vendors$Category, main="SAP Ariba Source Vendors", names.arg = vendors$SMVendorID, horiz=TRUE)
