SSRS subscription error

Hi all,

Ever set AX report for Subscription. I tried to subscribe on of AX report (let say CustListReport), but when it run, there is status error :

An error occurred while executing OnInit: The Microsoft Dynamics AX Reporting Data Extension does not support SQL Server Reporting Services Subscriptions.

Anybody know what is that all about ? I'm googling but cannot found any useful resources.

Thanks in advance,

Axl
