How to automatically process cube by "proactive caching"?

There is a function called "proactive caching" in Analysis services. It can:
----Automatic synchronization with the relational database
----No more explicit "cube processing

But I cannot have the latest data in the cube even I set the proactive mode as "real time"

Can anybody help me on this issue

Following is the procedures I have done:
1. test the data
1.1 use the bi dev studio to browser the cube, ensure no new data are there
1.2 process the the cube and browser the data, ensure new data are there
1.3 delete new data from source database and reprocess the cube, ensure no new data are there
1.4 add new data again

2. configure the proactive setting of cube
2.1 use sql server management studio to open the cube and open the properties window
2.2 in the option of "proactive caching" select "low-latency MOLAP" (even real-time ROLAP later), then click ok

3. configure the proactive setting of cube
3.1 open the patitions view properties window

3.2 in the option of "proactive caching" select "low-latency MOLAP" (even real-time ROLAP later), then click ok

3.3 in the notification tab, select "sql server " and specifiy tracking tables to the "fact table", which is a view to get data from real fact table.

4. wait a period of time...

5. test the data again
5.1 use the bi dev studio to browser the cube, but no new data are there (even I selected real-time ROLAP later). I even tried the reconnect and refresh options in the tool bar

So my questions are :
1. Did I do the right thing to achieve the target "Automatic synchronization with the relational database "

2. Can I monitor the procedure of synchronization, such as monitoring the log of processing, viewing the schedule setting and status of the process



Thanks a lot!
