Hi
1. Are you going to install the SAP system on Distributed or Cluster environment?
2. If it is Cluster environment in which OS / DB ?
3. If you are install the SAP on distributed system both services are installed on standalone
4. Kindly read the installation guide of SAP on Distributed and Cluster systems. I think still you are confused you can refer the SAP link - http://service.sap.com/guidefinder - Select the OS / DB & SAP version.
