R Integration with SAP HANA

Here are the prerequisites you must have before trying your hands on “R”

HBDCLIENT

HDServer

R-ODBC Package

R Studio

Setup the Data source (in this case SAP HANA DB Server)

Go to Service Marketplace -> Software Downloads -> Support Packages and Patches -> A-Z –> H–> SAP HANA PLATFORM EDITION” –> SAP HANA PLATFORM EDIT. 1.0” –> Entry by Component” –> HANA client

Once you have installed HANADBClient in your system then you need to setup data source.

Go to -> Control Panel -> Search for data Source (ODBC) -> Set up data sources (ODBC)

You will get the below popup

On Current tab click on Add one popup will appear for Server/Port information

Enter any data source name/any description for server ad then enter server: port –  if you don’t know the server and port name go to your hana studio (SAP HANA Development perspective) and right click on system then click on properties tab -> Additional properties tab -> Host details. After entering these details click on connect to check if the details are correct or not by entering the username/password if all ok then you get a prompt on connect that connection is successful.

Once you are done with above now download the R Studio and R package.

Now install both the Components once you are done with R Studio installation download the RODBC package goto your R Studio now & all install r Studio package.

Once we have added the RODBC package now we can check on R studio using library function

Now we can go ahead for accessing our HANA database artifacts, establish the database connection using R commands & then execute sqlQuery function for executing sql commands on R.

I created one table in HANA server for billing docs that I am accessing using “R” below is the sample code.

library (‘RODBC’)

ch<-odbcConnect(“data source name”,uid=”test_hana”,pwd=”test12″);

sqlQuery(ch, ‘SELECT * FROM “_SYS_BIC”.”BILLING_DATA” ‘)

result ->

Here is the output from “R”

Another sample for consuming procedure in “R”

I created one procedure which returns Company Code , Accounting doc & fiscal year from BSEG table.

sqlQuery(ch, ‘CALL “ABAPDEMO”.”GETDATA”(10 , ? )’);

Output in “R”

Your suggestions/questions/improvements are most welcome, I will try to share more sample codes as I will move on.
