Purpose The idea to implement this scenario came up when we had a requirement to transfer information from Cloud system to SAP CRM and back.SAP CRM system would in turn connect to SAP HANA get the results and send the result back to cloud system. As the requirement was to look for very quick results, I came up with scenario where we connect SAP PI directly to HANA to speed the process.

Abstract In order to establish a connection between SAP PI and HANA system, we need SAP HANA JDBC driver. The following document describes about getting the JDBC driver, using SAP HANA Studio to see the database tables and set up a sample scenario in PI to insert records into HANA database tables. Following document describes about the steps required to establish a connection between SAP PI and HANA system. 1. 2. 3.

Using SAP HANA Studio Using the JDBC Driver PI configuration

Description Using the SAP HANA Studio

SAP HANA Studio is a tool for developers who wish to create data models and stored procedures. We will use SAP HANA to view the database table that is updated via this scenario. Install SAP HANA Studio on your workstation. To use SAP HANA Studio you need to know the name of your SAP HANA user account and its respective password. This information can be obtained from your local database administrator. Please note that access to some schemas (catalogs of data models and objects) is restricted. Adding a HANA system to Studio 1. 2. 3. 4.

Make sure you are Administrator Console Right click on the navigator view. Select Add System from the context menu In the dialog window that appears enter the following Hostname: zzz-xx-yy.wdf.sap.corp (Your HANA system host name ) Instance Number: 01 (HANA system instance number) Description: HANA demo system   




5. 6.

Click on “Next”

Please enter the name of the system or personal user name you have been given by your system administrator, the respective password and then




7.

Click Finish. If the data entered is correct, a half expanded tree structure will appear in the Navigator view with the name of the system as its top node. Please double-click on the Catalog. Under that node you will find the nodes Authorization and Public Synonyms as well as a number of entries which represent database schemas.




8.

Click the Schema node, and then the table node. You will see the tables that you want insert records into

Using the JDBC Driver To access SAP HANA from PI, you have to first deploy SAP HANA JDBC Driver on PI Server.

Installing the JDBC Driver Since the SAP HANA Studio was written in Java, the JDBS driver is installed along with the SAP HANA Studio and can be obtained from this installation. It can be found in: /plugins/com.sap.ndb.studio.jdbc_.jar on Linux or UNIX platforms and on Windows platforms in \plugins\com.sap.ndb.studio.jdbc_.jar Note: within the Jar files, you will have to navigate to the following path com.sap.db.jdbc.Driver, to extract the Jar file that should be deployed on PI server:

Loading the JDBC Driver Please use the forName method of the Class in the Java platform: Class.forName("com.sap.db.jdbc.Driver");




Connection URL In the connection URL, you define the properties of the connection to the database instance. Syntax jdbc:sap://[:][/?[&]...] Name of the database computer Port of the SAP in-memory computing engine instance. ,,... Properties of the connection Example jdbc:sap://localhost:30115/? reconnect=true Using this connection URL, you set up a connection to the database instance from PI adapter.The port number used by the SAP in-memory computing engine is 30115. The connection options select the reconnect to true.

Now you are all set to go. 1. 2.

The database tables are accessible. JDBC driver is deployed on the server.

All that is required now is to configure the JDBC adapter in SAP PI to establish the connection to the database.

Configuring JDBC adapter in SAP PI

PI can now communicate to HANA system and send information back and forth.




Test Result Following is the result of a scenario which inserts table into the HANA database table.

Input File:

Execute your scenario and Check in Runtime Workbench:

You can now check in HANA studio using SQL query to verify whether the record has been inserted:
