Salesforce.com integration with SAP BW

Hello BW experts,

I've got a requirement to intregate Salesforce.com CRM system directly with SAP BW. The client is currently using SAP PI to get the data in ECC and reporting on top of it but for some areas they want direct integration. As the client will go for BW now, I wanted to know if we can directly integrate both the systems. Any input is highly appreciated.

Thanks,

AG
