R integration with SAP HANA

[shivamshukla12]

Hi -  Just thought to share about my new passion about “R” , I would like to share my newly experience with R (using R Studio) and its integration with SAP HANA , for the beginners it would be really helpful to follow the below steps and a smooth integration with R studio , enjoy accessing HANA artifacts easily like accessing the tables/view information & Consuming procedures , intention is let the people know the integration & want to share more later on this topic once I am friendly in “R” development fashion -  “still in learning mode” J.

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

Another step by step procedure to Download the SAP HANA Client -

https://www.stechies.com/install-sap-hana-studio-hana-client-windows-system/#SAP-HANA-Client-Downloa...

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 goto 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 (https://www.rstudio.com/ ) and R package (https://cran.r-project.org/ )

Now install both the Components once you are done with R Studio installation download the RODBC package (https://cran.r-project.org/web/packages/RODBC/index.html )  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 on procedure which returns Company Code , Accounting doc & fiscal year from BSEG .

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.

 

Thank you!
