The cache issue about indexcol function

Question

Hi Experts,
We have one requirement as below,
Firstly, we have some columns prompt created by JAVA in external portal page, not OBIEE internal prompts,such as Year, Month,Day.
Secondly, we have one report contains one dynamic column which showes the lowest selected level value.
For example,
When users muti-select value in Year, and not select Month,Day, so this report will display as below:
Dynamic--------Sales
2010-------------1000
2011-------------2000
When users muti-select value in Year and Month, and not select Day, so this report will display as below:
Dynamic--------Sales
201001-----------100
201002-----------300
201101-----------500
When users muti-select value in Year , Month, and Day , so this report will display as below:
Dynamic--------Sales
20100101--------50
20100202--------80
20110101--------100
So we have one method to solve this requirement, but faced new cache or update issue immediately. More detail information as below:
We create one temp table which has one flag column ,
when users select Year level, it will record 0,
when users select Month level, it will record 1,
when users select Day level, it will record 2
Then import this temp table into physical layer, and create session init block like below:
select flag from temp
Finially, we create new indexcol column in BMM :
INDEXCOL(VALUEOF(NQ_SESSION.FLAG),Year,Month,Day) and drag it into presentation layer.
When users select value in Year or Month or Day, and the flag will be record into database.However, the dynamic column in report will not be changed.
I must click "Reload Server Metedata" firstly, it will show correctly.(Users do not click this )
Is there any better method to solve cache issue? Or any other better methods for solving this requirement?
Thanks very much.
Note: I have disabled the cache in temp table in physical layer.

Sorry to bother you again, I found I was wrong in describing my problem. I found out that I sent the CiscoIPhoneExecute xml to the phone last time, not the CiscoIPhoneImageFile xml.
The CiscoIPPhoneExecute xml is like:
http://192.168.1.2:8080/test/push2phone.jsp?action=get"/>
And "http://192.168.1.2:8080/test/push2phone.jsp?action=get" returns the CiscoIPPhoneImageFile xml, like this:
Image Title goes here
Prompt text goes here
0
0
http://192.168.1.2:8080/test/pngs/attention.png
so when I send the CiscoIPPhoneExecute xml to a phone, the phone will display the file attention.png on the screen with the sound chime.raw, then I press the "exit" button, the attention.png on the screen disappears. But if I then send the CiscoIPPhoneExecute xml with the "http://192.168.1.2:8080/test/push2phone.jsp?action=get" that returns the CiscoIPPhoneImageFile that contains a different png file, for example "warning.png", the "attention.png" will appear for a short time during the time when "warning.png" is downloading, then "warning.png" appears. I have no idea why that happens. I don't want to see "attention.png" when I'm sending "warning.png". What can I do?
I've tried to directly sent the CiscoIPPhoneImageFile xml to a phone, everything goes well, no "cache" problems. but I have no idea how to add the sound "chime.raw". I want the png files to be sent like short messages with sounds. Please help!
Thanks a lot.
