using Cascading parameters in ax2009 reports

Hi, 

Please help me out in finding the solution to my problem. This is very 
urgent. 

I am creating a AX 2009 SSRS report. In the report I have two 
parameters, based on the first parameter which is a drop down , the 
second 
parameter needs to be filtered with specific values. For eg AccountNum 
is the 
first parameter which displays all the CustomerId. Based on the 
AccountNum selected, the second parameter should display the 
AppointmentNumber. Can you 
let me know how to achieve this scenario. Is this scenario possible in 
AX 
2009 SSRS? 

Thanks in advance
