Querying Data from 3rd Party System

We would like to query data from a 3rd party (non-SAP) system. Our BW is an MSSQL DB and the 3rd party is also an MSSQL DB. We do not want to physically load the data from the external system we just want to use the BW query tools to display the data.

Is this possible? I thought this is what a Remote Cube would be used for but SAP's instructions on Remote Cubes are vague and confusing.

1. In BW, create a source system for the external system that you want to use.

2. Define the required InfoObjects.

3. Load the master data:

· Create a master data InfoSource for each characteristic

· Load texts and attributes

4. Define the RemoteCube

5. Define the queries based on the RemoteCube
