What is best way to connect Web Dynpro for Java application deployed in SAP portal to connect to SAP HR ?

Is it good practice to connect to underlying SAP database ( eg oracle) directly to get the data or is there a better way ?

This below article describes to connect to external DB, however Is there any other way for SAP HR ?

Hi,

There are 2 supported ways :

First is to use JCO connections to call abap RFC enabled function modules. (BAPIs for example)

Second is to call SOAP web services (HR enterprise services for example)

You should never access directly database tables...

Regards,

Olivier

Hi,

if we have a custom table created in HR for customization purpose and need to access that table

Then you create a custom RFC enabled function module (or web service) to access this custom table.
