u need to install Transports and then roles through ur SAP Basis People. Whether SAP connector to be installed I am not sure..if u dont have then u have to Install it from the downloads I think.. Give a try see in the downloads if there are any SAP connector Downloads.
See the new Connector 5.3. Previously you can download, only downloads with the SAP Connector. Now u can also download through Olap Connector and DSO Connector. I am trying too.. So download and there is also documentation, how to assign the roles etc. I did not do any Application.. I am just trying too..
