SSRS 2005 Report Builder with Dynamics Ax 4.0

Hi,

Thanks in advance.

As Ax 4.0 supports integration of SSRS 2005 with reporting services as we all know.

But with Report Builder we have little customization, then what is the use of report builder as every thing we can do with AOT Reports and Web reports.

I know SSRS reports are dynamic and AOT Reports are static, apart from this can any one explore on SSRS with Ax 4.0

Thanks
