System environment requirements for creating Crystal Report from BEx Query

I need to set up an environment to create Crystal Reports from BEx Query and then save the Crystal Reports in BW system. But I cannot open the Crystal Report after saving. It would be best if we can create Crystal Report WITHOUT BOE. Is there any articles I can used as a reference for this scenario?

Currently my environment includes: BW system using NW 740, and Crystal Report 2011.

In order to create Crystal Report from BEx Query I selected SAP-->Create New Report from a Query. And then save the report to BW system under a role in the systems.

Thanks in advance for your help.
