Business One Integration with Non-SAP Systems

I am working on setting up a Scenario where a File will be dropped into File System & then imported in to SAP Business one to create Sales Order in SBO.

I am not able to define a System in System Landscape in Control Center with System Type other than SAP System. I tried creating a new XML file at following location "C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\B1iXcellerator\setup\com.sap.b1i.repository\SysType.xml". But it is not reflecting in Control Center.

Please help.....
