I was recently evaluating various approaches to integrate Siebel and SAP R/3 systems especially using Oracle SOA Suite. Siebel already provides a Siebel EAI Connector for SAP R/3. This is a tight coupling between Siebel and SAP R/3. If you are planning to use Oracle SOA Suite, it provides the iway adapter for both Siebel and SAP R/3 end systems which makes it possible to decouple the 2 end systems and integrate them. Both approaches are explained below.
Siebel EAI Connector for SAP R/3
The Siebel EAI Connector for SAP R/3 provides connectivity using BAPI and IDOC transport adapters, and predefined business processes. Using the connectors, you can exchange customer, order, and product information between a Siebel application and SAP. This leverages Siebel Workflow and Business Service data maps which are the transformations for the data entities like (Account in Siebel to Customer in SAP or Product in Siebel to Material in SAP). There are some pre-built integrations between common business processes and it also allows custom integrations to be built.

Integrating using Oracle Siebel Adapter
We can also leverage Oracle Fusion Middleware and the available iway adapters for Siebel and SAP end systems. Ensure that the Siebel Business Services (WSDL) or Business Objects (XSD) are available from Application Explorer for WSDL/XSD generation. Similarily ensure that the SAP BAPIs/IDocs are available in Application Explorer for WSDL/XSD generation. After that you can create the fusion processes to integrate the 2 end systems.
Below is a screenshot from Application Explorer once you create a target and connect to Siebel system.
