Use standard R functions and the development environment of your choice to analyze SAP Fieldglass data with the CData JDBC Driver for SAP Fieldglass.
Access SAP Fieldglass data with pure R script and standard SQL on any machine where R and Java can be installed. You can use the CData JDBC Driver for SAP Fieldglass and the RJDBC package to work with remote SAP Fieldglass 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 Fieldglass and visualize SAP Fieldglass data by calling standard R functions.
Install R
You can match the driver's performance gains from multi-threading and managed code by running the multithreaded Microsoft R Open or by running open R linked with the BLAS/LAPACK libraries. This article uses Microsoft R Open 3.2.3, which is preconfigured to install packages from the Jan. 1, 2016 snapshot of the CRAN repository. This snapshot ensures reproducibility.
Load the RJDBC Package
To use the driver, download the RJDBC package. After installing the RJDBC package, the following line loads the package:
library(RJDBC)
Connect to SAP Fieldglass as a JDBC Data Source
You will need the following information to connect to SAP Fieldglass as a JDBC data source:
- Driver Class: Set this to cdata.jdbc.sapfieldglass.SAPFieldglassDriver
- Classpath: Set this to the location of the driver JAR. By default this is the lib subfolder of the installation folder.
The DBI functions, such as dbConnect and dbSendQuery, provide a unified interface for writing data access code in R. Use the following line to initialize a DBI driver that can make JDBC requests to the CData JDBC Driver for SAP Fieldglass:
driver <- JDBC(driverClass = "cdata.jdbc.sapfieldglass.SAPFieldglassDriver", classPath = "MyInstallationDir\lib\cdata.jdbc.sapfieldglass.jar", identifier.quote = "'")
You can now use DBI functions to connect to SAP Fieldglass and execute SQL queries. Initialize the JDBC connection with the dbConnect function.
To authenticate, you will need to specify the Username, Password, APIKey, and EnvironmentURL connection properties.
To obtain an APIKey, log in to the SAP API Business Hub and click on Get API Key.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the SAP Fieldglass JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.sapfieldglass.jar
Fill in the connection properties and copy the connection string to the clipboard.

Below is a sample dbConnect call, including a typical JDBC connection string:
conn <- dbConnect(driver,"jdbc:sapfieldglass:EnvironmentURL='https://myinstance.com';Username=myuser;Password=mypassword;APIKey=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx;InitiateOAuth=GETANDREFRESH")
Schema Discovery
The driver models SAP Fieldglass APIs as relational tables, views, and stored procedures. Use the following line to retrieve the list of tables:
dbListTables(conn)
Execute SQL Queries
You can use the dbGetQuery function to execute any SQL query supported by the SAP Fieldglass API:
audittrails <- dbGetQuery(conn,"SELECT Id, Category FROM AuditTrails WHERE Company = 'CData'")
You can view the results in a data viewer window with the following command:
View(audittrails)
Plot SAP Fieldglass Data
You can now analyze SAP Fieldglass 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(audittrails$Category, main="SAP Fieldglass AuditTrails", names.arg = audittrails$Id, horiz=TRUE)
